Internet telephony — or Voice over Internet Protocol (VOIP) has the potential to transform the world of voice communications more profoundly than anything since the invention of the telephone itself. As telecommunications incumbents and a range of new entrants begin rolling out commercial VOIP services, policymakers around the world are grappling with the regulatory implications. In the United States and the European Union, the two largest nearterm VOIP markets, efforts are underway to fit VOIP into existing regulatory frameworks. This process of "regulatory classification" is by no means a purely administrative act. A lot is at stake and different interest groups have therefore mobilized to shape the respective outcomes. Because legacy regulatory systems in Europe and the United States differ, the regulatory treatment of VOIP in the two markets is beginning to differ as well. Yet in both markets there is a substantial danger that fitting VOIP into existing classifications will force VOIP to look more like regular telephony, thereby limiting its innovation potential.

The politics of regulatory classification
Over the next decade, telephony is going to change more dramatically than it has over the past one hundred years. The rise of Internet telephony or what experts call VoiceoverInternetProtocol (VOIP) represents a watershed in the history of telecommunications. Since the days of Alexander Graham Bell, voice communication has consisted mainly of linking a device designed exclusively for voice communication (called a "telephone") to a network designed to carry voice traffic (called a "telephone network"). VOIP turns voice communications into just another application on the allpurpose data network called the Internet. Software replaces the telephone. Any device equipped with such software a computer, a personal digital assistant, a sophisticated headset, or just a box that looks like a telephone that is connected to the broadband Internet can serve as a terminal for voice communications. Turning telephony into a software application enables stunning new services and features, from dramatically enhanced sound quality through global call forwarding to seamless integration with video. Best of all, all of this comes at dramatically reduced cost.
Given these attributes, it does not take an oracle to predict that VOIP will increasingly replace conventional telephony over the next decade or two. In the network backbone, this has already happened. Many operators now route international calls over IP networks, leading to significant savings that have slashed international calling charges to often just a few cents a minute. VOIP has been similarly successful among highend business users. Traffic to and from call centers and among the offices of globally operating companies increasingly bypasses conventional telephone networks. With the rapid diffusion of broadband Internet access, VOIP is now being rapidly adopted by the residential customer market as well. Pioneers in the United States such as Vonage, which was serving over 600,000 customers at the end of March 2005, and virtually all leading operators in Europe and the U.S. are hastily working on their VOIP strategies.
That we are transitioning into a world of VOIP seems clear. How we will get there is not. A principal driving force on the transition path will be regulation. Telecommunications is a tightly regulated industry, partly because of the strategic importance of voice communications for economy and society, partly because of the externalities that characterize network industries, and partly simply because of political legacies. How existing regulation will be applied to VOIP and the content of potential new rules will shape the evolution of technology and markets. Among the most pressing regulatory issues are the interoperability of VOIP with existing networks, access to emergency services, network security, wiretapping, numbering, and universal service funding.
That we are transitioning into a world of VOIP seems clear. How we will get there is not.
All of these issues are no doubt important. But the one that stands out both with respect to the attention it has received by regulators so far and in terms of its importance for the future of VOIP is what we may loosely call "regulatory classification." From a practical point of view, classification stands out because classifying different services is what regulators principally do. In an ideal world, one could just draw up rules for VOIP that address the aforementioned critical issues, keeping in mind the technology’s novelty and the substantial differences that exist between conventional circuitswitched telephony and innovative packetswitched VOIP. In the real world, however, a first step in the regulation of new technologies is usually to try to fit them into existing service categories, in part because those are the tools that regulators work with and in part because classification can provide shortcuts through complex regulatory problems. Alternatively, regulators may be inclined to ask whether VOIP service is "like" or "substitutable" for current services an approach that may obscure technological achievement. Either way, much is at stake in these decisions.
Fitting VOIP into existing regulatory categories is not simply an administrative or technical act. Since categories are associated with distinct sets of rights and responsibilities that have distributional and market strategic implications, a large number of stakeholders have mobilized to affect the outcome. We thus inevitably enter the realm of politics. Here we mean "politics" with a small "p" that is, the complex back and forth among powerful interests that overshadows what are nominally purely administrative processes. Parliaments and elected governments have so far barely entered the fray. But this does not mean that the process is not political.
Unpacking the political economic dynamics of evolving VOIP regulation highlights a second, more analytic reason to focus on classification. The debate over how to classify VOIP represents the leading edge of the question whether regulatory classification is useful in a world of converging technologies. In other words, precisely because VOIP forces the convergence of previous era telecommunications and the Internet, we ought to pause and ask whether regulation from that previous era still makes sense.
This article then has three main objectives. In part one, we first show why VOIP will be regulated, next we sketch issues that require regulatory attention, and then we elaborate on why most attention is currently focused on classifying VOIP services based on existing regulatory frameworks. In part two, we explain the distinct regulatory systems in the European Union and the United States, and analyze efforts to date to treat VOIP under these systems. In both markets, politics and interest diversions among stakeholder camps dominate the process. In spite of different regulatory systems and industry structures, regulatory responses that sprung from distinct perspectives are struggling with similar challenges. In the third part we then open up the debate and analyze more closely the political issues that run through the narrow technical debates over classification. Regulators are vying for influence and are fighting over the allocation of regulatory authority. Incumbents in the United States and Europe are adopting different strategies towards this new technology. New entrants are fighting for market rules that allow them to take on the incumbents. Meanwhile policymakers are struggling to maintain those aspects of the current system that address historical political problems, like consumer welfare and taxing of services, regardless of inadvertent, but negative, effects that may have on evolving markets and technologies. Those negative effects include disparate treatment of competing products on the basis of historical distinctions between, for example, telephony and cable television. The article concludes with some critical reflections. VOIP has tremendous innovation potential and will transform the way we communicate. It provides vast opportunities for new services that will create real value for consumers. Policymakers should thus contemplate harnessing the transformative potential of VOIP to drive a modernization of telecommunications regulation as well. Were that to happen, VOIP would indeed signal a new era on all fronts.
The rapid rise and inevitable regulation of VOIP
VOIP has been phenomenally successful in just a few years. At the end of 2003, residential VOIP in the United States basically did not exist. By the end of 2004, 400,000 American households had signed up for VOIP services. Industry observers forecast 12.1 million U.S. households to use VOIP within just five years . These optimistic projections are backed up by spectacular growth over the last two years in Japan. There, ten percent of households use VOIP to make calls just two years after such services were introduced . Voice service has quickly become a standard feature of broadband packages. More than 90 percent of Yahoo BB’s three million broadband subscribers in Japan, for example, have also signed up for VOIP. Last year’s government auction of roughly nine million VOIP telephone numbers indicates where policymakers believe the industry is headed . Europe, finally, has been the region of the world with the fastest growth of VOIP minutes, though much of this comes from highend business users .
One driver of this success is greater efficiency. Rather than dedicating an entire circuit to a single voice communication, VOIP divides up the audio signal in packets and routes them over the allpurpose Internet. Yet efficiency alone is only part of the story. Whereas ordinary circuitswitched telephony is capped at 64kbps by network design, VOIP can support communication with higher bandwidth. This allows for much better voice quality and the bundling with other applications such as simultaneous text or video messaging. Business users in particular find the ability to seamlessly integrate voice communications into Internetenabled productivity and distance collaboration applications enticing.
A second cluster of VOIP advantages centers on mobility, or what experts are calling "nomadic" applications. Just as one can check personal email and surf the Web from just about anywhere in the world, a user can receive VOIP calls to a single number anywhere she is connected to the broadband Internet, whether wired or wireless. Think of it as a universal provider and technologyindependent global roaming service. These nomadic dimensions will enable a whole range of new services, particularly when combined with technologies such as ENUM that permit the bundling of diverse communications services like fixed telephony, wireless telephony, fax, email, and instant messaging under a single identifier .
Exciting as these new efficiency, quality, and service aspects may be, it is the transformative potential of the VOIP architecture, offering unimaginable future services, that holds the real excitement. This stems principally from its inversion of the previous logic underpinning telecommunications network design. The old, circuitswitched world is networkcentric. Any new service such as call waiting, call forwarding, or threeway calling in recent memory requires complex network reengineering. This architectural limitation is one reason for the low level of innovation in telephony over the past century. The new, packetswitched world, in contrast, is application or usercentric. New applications and services can be implemented through software, predominantly on the user side, and network reengineering becomes the exception, rather than the rule . This is a world of userdriven innovation and rapid change .
This paradigm shift is too big and too important for anybody in the industry to ignore. Indeed, both new entrants and incumbents have mobilized considerable resources to get onto the VOIP train. In the U.S., aggressive new entrants such as Vonage have received most of the attention. But leading local incumbents such as BellSouth, SBC, Qwest, and Verizon are preparing their own VOIP strategies. The picture is similar in Europe, though there has so far not been a powerful new entrant that would shake up the industry as much as Vonage has done in the U.S. Among Europe’s incumbents, British Telecom has been the most ambitious, pledging to move to an allIP network in the U.K. by 2009. France Telecom’s Wanadoo and TeliaSonera of Finland and Sweden are some of the other early movers. In addition, a range of new entrants, including Vonage, Lingo, Indigo Networks, and VozTelecom have begun to target business users or have plans to offer residential VOIP service. Vonage, lastly, has begun entering the European market, initially targeting the U.K.
What we have then is a situation where companies from both worlds circuitswitched telecommunications and the packetswitched Internet pursue the new opportunities created by the convergence of underlying technologies and the rise of packetswitched voice services. Most experts are fairly confident that circuitswitching will be a thing of the past before long. Yet how we will get there, who rides the transformative wave most successfully, and who gets stranded in the process, is far from clear.
Most experts are fairly confident that circuitswitching will be a thing of the past before long. Yet how we will get there, who rides the transformative wave most successfully, and who gets stranded in the process, is far from clear.
Regulation will play a crucial role in this transition. Law and policy set critical ground rules that structure market competition. This is true in all industries. In the case of VOIP, however, regulation assumes an even more important role. Precisely because it is an instance of converging technologies in which companies from previously distinct industries compete against one another, the content and underlying logic of regulation has the potential to critically affect who wins and who loses in the marketplace. How should rules that were designed for a world of circuitswitched voice telephony apply to a world where voice communication is just another application on the allpurpose Internet? This is not just a question of law and jurisprudence. It is very much a political question and the answer to it will undoubtedly leave a big footprint on VOIP markets and the industry as a whole.
Why regulation is inevitable … and difficult!
There is a fundamental difference between VOIP and previous IPpowered innovations such as email or Instant Messaging: these latter technologies burst into a new, unregulated space. There was no market for email prior to the commercial diffusion of email, for instance. There were no market rules, no incumbents used to operating under these rules, and no past policy objectives dependent on the execution of the rules. By contrast, VOIP services inevitably run headlong into traditional telephony regulation, characterized by detailed oversight and commoncarrier obligations . Over the course of more than a century, policymakers have devised a dense set of rules and regulations covering emergency services, network integrity, universal access, and the allocation of scarce identifiers such as telephone numbers, to name just a few. As VOIP displaces current telecommunications technologies, it will inevitably be confronted with these regulatory legacies.
Not only is a regulatory vacuum for VOIP impossible to imagine, it is also not in the interests of market players, including new entrants. Access to the Internet, especially for residential customers, is a necessary predicate for the use of VOIP services. And that means that VOIP providers (if they are not broadband network providers themselves) need to supply their services over other providers’ broadband lines, a circumstance that, in turn, makes many VOIP service providers dependent on open access policies . Likewise, interconnection requirements are necessary to ensure that VOIP providers can offer their customers the ability to call any telephone user, whether VOIP or conventional. Third, new VOIP providers need unfettered access to the allocation of telephone numbers in order to compete with incumbents on a levelplaying field. As long as regulatory uncertainty regarding these and other issues prevails, the benefits of competition and innovation cannot be reaped to the fullest possible extent.
That regulation of VOIP is inevitable, however, does not mean it is easy. VOIP is confronted by a whole range of regulatory legacies from the previous era. While many still make sense particularly in a hybrid world where technologies and market players from both worlds will compete and coexist others may have run their course. Regulators on both sides of the Atlantic are currently busy sorting through a complex web of regulatory issues created by the clash of old and new. Among the most critical issues that have to be addressed are:
Access to emergency services such as 911. Standards for network reliability and security. Network interoperability and interconnectivity. Provision and funding of universal service. Wiretapping access for law enforcement. Allocation of numbers and other identifiers.
However, rather than considering each of these issues in isolation, regulators from Washington to Brussels have focused most of their attention on regulatory classification. From a regulator’s perspective, this makes sense. Deciding from scratch each time a new technology or service comes around which provisions of the law apply and how they should be implemented is tedious and, more importantly, opens the door to arbitrariness and inconsistencies. So if you ask a regulator whether provision "P" applies to a service "S," she will probably respond that it depends if "S" is a service of type "A," "B" or "C," for only services of type "A" have to comply with provision "P." The same is now happening in the case of VOIP. Rather than arbitrarily deciding which provisions of existing regulation should apply to VOIP and how they should be implemented, regulators are trying to determine what kind of an animal VOIP is and where it falls in the context of existing frameworks. From a regulatory point of view, once there is an objective set of criteria to distinguish different kinds of VOIP services, and to compare and contrast legacy and new services, settling a whole range of regulatory issues becomes simple. The nameofthegame of evolving VOIP regulation, in other words, is classification.
Classifying VOIP in the U.S.: Circuitswitched policies meet IP
IP networks are now fully capable of carrying voice communications. That includes playing a role in traditional telephonetotelephone connections (typically in the "longdistance" network), through the use of Internet applications, like Vonage, over cable and wireless networks and, perhaps most importantly, as supplied by the owners of traditional circuitswitched networks, including BellSouth, Qwest, SBC and Verizon. So in the United States the technology is ready. Is the world of regulation?
Application of regulatoryclassification categories requires, first, an understanding of who is entitled to do the classifying. On 9 November 2004, the Federal Communications Commission (FCC) took a big step toward answering this question when it preempted the ability of the state of Minnesota to apply its traditional telephoneutility regulation to Vonage’s IPtelephony service. In its Vonage Order, the FCC ruled that Vonage’s DigitalVoice service, as well as similar services such as those offered by cable companies, could be regulated only at the federal level because those services were not, and could not be, limited to the geography of a single state . This is a distinctly different outcome than the jurisdictional oversight of traditional circuitswitched telephony that, because of the geographicallyfixed location of its users, could be divided fairly neatly between "intrastate" and "interstate" services. State regulation of "local" telephony, typically lodged in a state public utilities commission, is thus a tradition of long standing.
So in the United States the technology is ready. Is the world of regulation?
However, in the Vonage case, the FCC reasoned that no aspect of VOIP service could be classified as only "intrastate" because, given the technological characteristics of a movable, packetbased service, Vonage’s offering "cannot be separated into interstate and intrastate communications."
The FCC left itself with a lot of work to do because it now has the obligation to fashion the rules governing VOIP. Must VOIP providers contribute to the universalservice funds that provide subsidies to rural and lowincome customers? Do VOIP providers have any obligation to exchange traffic with other voice providers and, if so, under what financial terms? Must VOIP providers ensure any level of network or performance reliability? Must VOIP providers collect taxes or fees on the services they provide and, if so, which ones? These are only some of the question that, in the U.S. context, turn on the regulatory classification into which VOIP services are placed . The FCC took the first step in answering these questions when, in June 2005, it ruled that "providers of interconnected voice over Internet Protocol" service must "supply enhanced 911" capabilities to their customers .
One place to start in answering these questions is to understand how VOIP service fits into the established set of regulatory classifications. In the United States, the most important classification separates "information services" from "telecommunications services." The importance of this distinction comes from the fact that, under U.S. law, an "information service" is presumptively free from regulation, although still within the jurisdiction of the FCC, while a "telecommunications service" is putatively subject to oldline common carrier requirements .
Two recent FCC rulings have created initial benchmarks for the application of this classification scheme to different types of VOIP services. In February 2004, the FCC ruled In the Matter of pulver.com that the company’s Free World Dialup (FWD) application was an unregulated "information service" subject to the FCC’s jurisdiction. In April 2004, in In the Matter of AT&T, the FCC ruled that "phonetophone" services are "telecommunications services" and, thus, subject to the interstate access charge regime applied to longdistance services generally, even if the communications are transmitted by means of IPprotocols for some portion of their transmission.
For practical reasons, the FCC could have scarcely ruled differently than it did in either case. The pulver decision involved an Internet application that facilitated the broadband transmission of voice "calls" without ever touching the traditional, circuitswitched telephone network. Its serviceprovider describes FWD as a free service "empowering the user community" to "to make real, free phone calls using your favorite telephone, computer or PDA and any broadband connection" .
The FCC emphasized, for example, that pulver’s servers offer services that are beyond the traditional reach of telephone networks, including information about other members’ online presence. Yet the agency kept open a door to exercise some authority. Although it concluded that the service was not a "telecommunications service" subject to the traditional heavy hand of traditional regulation, it was careful to maintain its jurisdiction to take administrative action in the future by concluding that the service was an "information service."
To have concluded that FWD was a telecommunications service would have raised the specter of oldstyle regulatory provisions applying to a host of Internet applications. Indeed, had the pulver ruling gone the other way, the FCC would have reached a conclusion inconsistent with its treatment of cable modem services. In its Brand X Order, the FCC ruled in 2002 that cable modem service was an "information service" but not a "telecommunications service" . That conclusion was just upheld by the United States Supreme Court, which deferred to the Commission’s judgement that "cable companies that sell broadband Internet service do not provide ‘telecommunications servic[e]’ as the Communications Act defines that term."  The Supreme Court ruling was embedded in the principles that define the relationship in the United States between "expert" administrative agencies, like the FCC, and the judicial branch of government. Although the Supreme Court found that Congress’ intent in the classification of telecommunications and information services to be ambiguous in some respects, it also concluded that the FCC had acted within its scope of responsibility in preferring to treat cablemodem services as inclusive only of "information services" without any separate "offering" of "telecommunications" services. As the Court explained, the provision of "information" and "telecommunications" services were "sufficiently integrated" to make it reasonable to "describe the two as a single, integrated offering."  That is because, in the Court’s judgement, "[a] consumer uses the highspeed wire always in connection with the informationprocessing capabilities provided by Internet access, and because the transmission is a necessary component of Internet access." 
Another, political, factor in favor of the conclusion reached in pulver was the fact that the FWD service had little impact on the flow of traditional telecommunications revenues and subsidies. The service was more of a hobbyist’s plaything than a substitute for the "normal" form of circuitswitched voice calling.
The same could not be said of the AT&T service. The AT&T Order dealt with what appeared to be a fairly obvious attempt to avoid access charges through the simple expedient of touching an IP network. In essence, AT&T would take a normal call originated on the circuitswitched network, move it temporarily to an IP packetswitched network and then convert it back to a circuitswitched call for the purpose of delivering it for termination on a local telephone network. To the callers, there was nothing about the call that seemed different from traditional circuitswitched telephony.
Indeed, that seemed to be the point of AT&T’s gambit. It was arbitrarily applying regulatory classifications, hoping, by the conversion of a transmission from analog to IP, to avoid the requirement of paying local companies the cost of interstate access calls. There were good business reasons for AT&T to seek this outcome interstate access charges are more expensive than other forms of delivering traffic for termination on local telephone systems but the FCC saw that a ruling for AT&T would lead to a collapse of the current accesscharge regime by carriers who would likely quickly follow AT&T’s example.
In light of Brand X, the FCC’s future applications of the terms "information" and "telecommunications" services are likely to stick. But, even in upholding the Commission’s judgment, the Court spotted a new tactic that could emerge from its decision.
The FCC’s AT&T Order discussed above was an attempt to avoid the regulatory burdens of "telecommunications" status. So, too, the Supreme Court recognized that its decision in Brand X could lead a telephone company to assert that the presence of datadriven services would have the regulatory impact of converting standard telecommunications services into a single, integrated informationservices offering. The Court dismissed that possibility, however, by explaining that it would not be enough, for example, for a telephone company to claim that telephone service plus voice mail constitutes an integrated "information" service:"That is because a telephone company that packages voice mail with telephone service offers a transparent transmission path telephone service that transmits information independently of the informationstorage capabilities provided by voice mail. For instance, when a person makes a telephone call, his ability to convey and receive information using the call is only trivially affected by the additional voicemail capability ... . By contrast, the highspeed transmission used to provide cablemodem service is a functionally integrated component of that service because it transmits data only in connection with the further processing of information and is necessary to provide Internet service." 
Of course, it takes no great leap of imagination to anticipate that a telephone company could take one step beyond the facts of the AT&T Order in order to recast the use of IP in light of the Court’s "trivial/necessary" distinction. After all, the telephone calls at issue in the AT&T Order were completed only by means of an IPtransmission, suggesting that IP was a "necessary" and not "trivial" part of the service AT&T provided. In that case, the FCC dismissed AT&T’s contention that it was offering an "information" service because, from a customer’s perspective, the service was the same as an ordinary telephone call. But it takes little imagination to conjecture that a telephone company could import some aspect of information management into the "call" itself, such as a bundled instantmessaging or documenttransmission capacity. The company would then test the limits of the "trivial/necessary" distinction by arguing that Brand X requires its IPassisted telephone services to be classified as "information" services, thus rendering them presumptively exempt from the norms of telecommunications regulation, including access charges, commoncarrier responsibilities and universalservice obligations.
The FCC wanted to ensure that the telecommunications networks were available as an "open" platform ...
One need not dive headlong into the "trivial/necessary" distinction, to recognize that the fundamental problem faced by the FCC which it is in no position to change is that the definitions of "telecommunications" and "information" services were devised to deal with very different market circumstances. Both terms derive from the distinction between "basic" and "enhanced" services created by the FCC in its famous Computer Inquiry line of decisions in the 1960’s and 1970’s before the breakup of AT&T .
Indeed, that’s the critical point. Faced with the traditional antitrust concern that the AT&T monopoly might impede competition in the separate, competitive market for data services, the FCC formulated definitions whose principal purpose was to constrain a regulated monopoly. Thus, the FCC wanted to ensure that the telecommunications networks were available as an "open" platform for the provision of competitive "enhanced" services and, through requirements of structural separation, that Bell companies could not leverage their telecommunications networks into unfair competitive advantage. Even when the definitions of "enhanced" and "basic" transmogrified into the statutory definitions of "telecommunications" and "information" services in the 1996, the dominant concern was that local bottlenecks not be used as the basis of unfair competition in competitive markets.
That justification is not the basis for current actions. There is no competitionpolicy objection to the widest proliferation of IPtelephony by whoever wishes to deploy it. (Indeed, competitionpolicy goals favor the introduction of new services). This means that the definitions of "telecommunications" and "information" services, much like horsedrawn buggies fitted with propellers, are being employed for purposes for which they were simply not designed.
But whether pulver and AT&T were rightly decided is almost beside the point. The hard question of regulatory classification of VOIP services remains to be decided. Indeed, perhaps more notable is what the FCC did not decide in the Vonage Order (the order in which the FCC affirmed federal, but not state, jurisdiction over VOIP). The FCC concluded its discussion of jurisdiction and thus its ability to exercise some oversight over VOIP services without confronting the obvious substantive question of whether the service involved was an "information service" itself. In other words, the FCC has conspicuously avoided addressing the heart of the matter: how to classify a service that uses IPprotocols to allow an enduser to use a device that looks like a telephone to institute a "voice" transmission that sounds the same at the end of the transmission as it did when spoken and is received by another enduser who is either on a telephone or is using a device that, in common parlance, is a "telephone."
Rather than deciding the question, the FCC, in its pending rulemaking has simply suggested a list of "functional and economic factors" to be considered in distinguishing "telecommunications" from "information" services. Those factors include:
- Functional equivalence to traditional telephony;
- Interconnection with the Public Switched Telephone Network (PSTN) and use of the North American Numbering Plan:
- PeertoPeer Communications vs. Network Services;
- Facility Layer vs. Protocol Layers vs. Application Layer. 
This list, on close observation however, demonstrates the problem much more than it suggests a solution. If these are the critical issues to be considered, what do they imply for the regulatory treatment of actual VOIP services? The FCC has asserted jurisdiction over VOIP services without confronting the most basic implication of its regulatory power how to treat VOIP services as a general matter under current law . Why has it confronted the edges of the classification issue without deciding the core principles under which VOIP is provided?
The FCC has asserted jurisdiction over VOIP services without confronting the most basic implication of its regulatory power how to treat VOIP services as a general matter under current law.
The recent issuance of the FCC’s order requiring "providers of interconnected" VOIP services" to supply enhanced emergency services to their customers conspicuously failed to address any of the larger questions . Citing a series of incidents in which VOIP users tried, but failed, to reach the emergency 911 services provided as a normal incident of circuitswitched telephony, the FCC concluded that "public safety" required the imposition of this obligation. The FCC said that the data before it "clearly indicates…that consumers expect that VoIP services that are interconnected with the [Public Switched Telephone Network] will function in some ways like a ‘regular telephone’ service and that, in this instance at least, such consumer expectations had to be fulfilled through regulatory action."
Obviously some classification was necessary in order to establish the boundaries of this new obligation. Thus, the FCC defined an "interconnected" VOIP provider to be a service that provides "twoway voice communications" that permit users generally to originate and terminate calls on the public, circuitswitched network . That certainly covers Vonage. But Skype, for one, says that it is not covered, on the ground that the order only applies to "replacement" services. Indeed, in the vernacular used by Commissioner Copps, the FCC rules "are directed squarely at substitutes for basic telephony" .
For purposes of this paper, however, the E911 Order is also important for what the FCC failed to decide. Again, the FCC declined to rule whether VOIP is an "information" or a "telecommunications" service (deciding that it has the authority to compel the E911 interconnection in either event). Again, the FCC declined to adopt a general set of rules for VOIP services. And again, the FCC declined to definitively analyze the "functional and economic factors" that could establish an overall framework for treatment of VOIP services. Instead, it seemed to proceed by applying the rules of circuitswitched telephony to IPservices that act (from the perspective of consumers) as a "substitute".
Despite the obvious importance of the publicsafety objectives served by the E911 Order, the longterm risk of a casebycase approach is, of course, that the FCC could be seen as acting in a way that is ad hoc and, potentially, arbitrary. It was to avoid such outcomes that led the European Union to adopt a set of "technologyneutral" classifications for communications services, an approach that now being applied to VOIP services.
Classifying VOIP in Europe: The first test for a new framework
In sharp contrast to the United States, Europe has recently modernized its telecommunications regulation with a deliberate focus on the implications of the Internet revolution. The principal aim of the reforms implemented by the European Union in 2002 was to induce more competition in a market still characterized by the legacies of almost a century of government monopolies. These government monopolies which simultaneously served as telecom regulators were not broken up by the courts, as in the U.S. Instead, competition was introduced gradually based on a negotiated framework. Liberalization began in parts of Europe in the 1980s but really only picked up steam in the 1990s when EU members committed to the separation of regulation from operation, the privatization of stateowned monopolies, and the gradual introduction of competition . Wireless became the first "test bed" for liberalization and the spectacular success of Europe’s GSM, in turn, provided further steam to the liberalization train .
Europe’s success in wireless, the challenges posed by the looming broadband Internet revolution, and the rather sluggish introduction of competition in fixedline telephony markets provided the justification for policymakers to revisit the issue of telecommunications regulation. Whereas the U.S. Telecommunications Act of 1996 had consciously maintained and affirmed the increasingly outdated categories of "information" and "telecommunications" services, the European Commission embarked on an ambitious mission to create a uniform, technologyneutral regulatory framework for electronic communications services. Because many former telecom monopolists had also owned their country’s cable networks, artificially distinguishing between these two legacy technologies at the time when digital advances drove convergence made little sense. As a result, fixedline telephony, cable, and wireless networks now fall under a single regulatory framework.
Making regulation technology neutral
Adopted in 2002, the new regulatory framework for electronic communications came into force the year after . The framework’s explicit objective is to provide coherent regulation for all transmission networks and services, regardless of underlying technology. In addition to fostering competition, the principal aims of the framework are to promote European market integration and to promote consumer interests. It permits companies to provide new electronic communications services based on a general authorization. No specific administrative authorization by a National Regulatory Authority (NRA) the equivalent of the FCC in each EU member state is necessary. It also establishes a right to negotiate interconnection agreements to existing networks. Most importantly for the case of VOIP, the framework defines three distinct types of communications services, each with its own set of rights and obligations:
- Electronic Communications Service (ECS) providers offer services for numeration that consist of the conveyance of signals over electronic communications networks. ECS providers have the right to offer their services anywhere in the EU, can obtain numbers, may negotiate interconnection agreements, and can request permission to install facilities on public property. In return, they must meet a variety of obligations. They must inform NRAs of their service offering, publish qualityofservice information, grant subscribers access to directory services, take steps to ensure network security, and safeguard the privacy of consumers.
- Publicly Available Telecommunications Service (PATS) providers offer telephone service for national and international calls to the general public, originate and terminate calls based on a national numbering plan, and provide access to emergency services. PATS providers enjoy all the rights and obligations of ECS providers. In addition, however, they must guarantee access to emergency services, permit number portability, and ensure network access at fixed locations in case of catastrophic network collapse. In exchange, they have the right to access carrier selection and preselection functions on networks with substantial market power, port numbers from other providers, and obtain telephone directory listings for their subscribers.
- Universal Service Obligation (USO) is fulfilled by at least one operator per jurisdiction and includes the provision of a minimum quality service at an affordable price. Any ECS or PATS can apply to become the USO provider for a given jurisdiction. Regulators can require all ECS or PATS to contribute to universal service funding, though they have the right to free providers with small market shares from such obligations.
The three categories are at the heart of European telecommunications regulation. Distinct rights and obligations are associated with each category, regardless of the underlying network technology. Only PATS providers, for example, have to guarantee access to emergency numbers. They also have to meet higher qualityofservice standards. In return, however, they have certain privileges that ECS providers do not enjoy. Precisely because assigning VOIP services to a particular regulatory category addresses questions about the rights and responsibilities of VOIP providers, the VOIP debate in Europe has centered on classification. The most important initiative to date in this respect is a consultation by the European Commission.
The European Commission wants to leave a choice…
Europe does not have a single regulator for telecommunications; there is no "EuroFCC." Regulatory authority is instead vested in the member states and exercised by the NRAs . As guardian of EU legislation, a central role in the regulation of VOIP nevertheless falls to the European Commission. To preempt uncoordinated member state policymaking, the Commission has launched a public consultation to determine how the EU’s regulatory framework applies to VOIP.
Consistent with the FCC’s pulver decision, the European Commission explicitly notes that computertocomputer voice communication that never touches the existing circuitswitched PSTN does not fall under the regulatory framework. Services such as Skype, for example, that rely on PCs as access terminals and therefore do not offer a full substitute for voice telephony are viewed as an "information society service" and are freed from conventional telecommunications regulation. Only VOIP offerings that qualify as "communications services" fall under the EU framework .
The critical question is whether VOIP providers that do seek to terminate calls over the existing PSTN and are thus providers of "communications services" should fall under either the existing ECS or PATS rules, or whether entirely new regulatory categories are necessary. Stressing that VOIP is a dynamic and evolving field with considerable business model experimentation, the Commission "does not propose any formal, rigid classification of different publicly available VOIP service offerings" . Instead, the cornerstone of the current proposal is to leave it up to individual VOIP providers to opt for regulation under either the existing ECS or PATS regime . Each category comes with specific rights and obligations and the providers, argues the Commission, should decide for themselves how to solve the inherent tradeoffs.
As ECS, VOIP providers would have to meet fewer regulatory obligations. Under current regulation, they need not ensure access to emergency numbers, for example. While the Commission notes that NRAs could technically oblige even nonPATS providers to ensure emergency access, it views such an obligation as disproportionate in light of current technical difficulties. Instead, it advocates that NRAs demand VOIP providers that opt for ECS treatment to inform consumers exactly how they handle the issue of emergency calls, if access is available, and if such calls are routed to the nearest emergency center based on location information.
As far as wiretapping, data retention, and other demands of law enforcement are concerned, the regulatory framework contains the same obligations for ECS and PATS. There is a difference with respect to network security, however. Again, the responsibility of ECS is lighter. While the Commission highlights that ECSopting VOIP providers would have to take steps against viruses or denialofservice attacks, the obligations of PATS are considerably greater. Again, the Commission appears content with adequate information of consumers of the security limitations of new VOIP service, both on the network level and with respect to the vulnerability of terminals to power failures.
Lastly, with respect to the critical issue of interconnection, the Commission’s proposal emphasizes the right of all electronic communications providers ECS and PATS to negotiate interconnection agreements. As far as IPtoIP interconnection is concerned, peering arrangements among ISPs should suffice. With respect to interconnection between IP networks and the PSTN, however, intervention of NRAs may be necessary to ensure competitive access.
Given the overall benefits of ECS status, why would VOIP providers opt for the more stringent requirements of PATS? One reason is that PATS providers enjoy considerably more extensive rights in the area of numbering, particularly with respect to number portability and directory listings, and potentially with respect to geographic numbers. The Commission advocates making both geographic and nongeographic numbers available to any VOIP provider, be they ECS or PATS. European consumers already have considerable experience with nongeographic numbers because these are used for wireless services. In fact, several industry analysts advocate using special VOIP prefixes to clearly distinguish VOIP from existing PSTN service. Conscious that a limitation to nongeographic numbers could disadvantage VOIP providers, however, the Commission calls on NRAs to make both types of numbers available. Yet the EU regulatory framework restricts the right to port to existing numbers to PATS. Only a PATS provider could guarantee customers can retain their existing phone numbers despite a switch to VOIP.
One might think that the industry would be happy about the Commission’s lighthanded approach. Letting operators choose what category they want to fall under seems businessfriendly. But this very much depends on where a company sees itself in the evolving market for VOIP services. Indeed, initial responses to the Commission proposals suggest that the proposed freedom to choose is likely to come with significant restrictions.
…but industry is split…
Industry has been generally supportive of the Commission’s proposals but various camps are taking different positions on specific issues. Indeed, it appears that rival industry camps are staking their claims on the issue of classification. A variety of stakeholders call for objective criteria to distinguish ECS and PATS providers. Former monopolists such as Germany’s Deutsche Telekom or Spain’s Telefónica for example are opposed to the notion that new VOIP providers may simply choose whether or not to comply with the PATS obligations that they themselves are subject to. Their argument is that VOIP providers ought to be treated as PATS if they offer publicly available telephony services via ordinary phone numbers as a substitute to existing PSTN services. Telefónica even wants NRAs to have the authority to change a VOIP provider’s status from ECS to PATS if market analysis suggests such services are offered as full substitutes for circuitswitched telephony. In such cases, argue the incumbents, new VOIP entrants ought to comply with all aspects of existing regulation, including access to emergency services and adherence to network security and qualityofservice standards. This position, interestingly, is also shared by several cable operators.
Since European broadband markets are still characterized by dominant former monopolists, new entrants are understandably concerned about adequate access to existing networks.
Potential new entrants to the European market such as AT&T, Vonage, or Pulver, in contrast, stress the importance of ensuring a levelplaying field even for nonPATS providers of VOIP services. Since European broadband markets are still characterized by dominant former monopolists, new entrants are understandably concerned about adequate access to existing networks. Predictably, they demand full access to numbering resources including geographic numbers even for ECS providers. In line with Commission proposals, they stress that it would be sufficient for nonPATS VOIP providers to simply alert customers of the inherent limitation of current VOIP technology in the area of emergency call routing.
…and the member states have their own ideas
The European Commission may have an important role in interpreting EU regulation and proposing potentially necessary changes, but implementation and actual regulatory decisionmaking authority is exercised by the NRAs. Several NRAs have begun their own VOIP consultations and a few have already handed down decisions. While regulators agree on some issues, different interpretations with potentially farreaching implications loom.
Among the most important decisions has been the Finnish regulator’s authorization of TeliaSonera Finland’s VOIP service, designed specifically for business clients. TeliaSonera is the product of the merger between the Finnish and Swedish former monopolists and is the first PSTN incumbent to offer VOIP on a large scale in Europe. The company targeted its VOIP product to existing broadband business customers and deliberately marketed it as a substitute for PSTN telephony service. Accordingly, the Finnish Communications Regulatory Authority, Ficora, ruled that TeliaSonera would have to comply with the same regulation for this VOIP as for its conventional PSTN offerings. It officially classified the offering as a PATS service because it is first, available to the public; secondly, users originate and receive national and international calls and have access to emergency services; and thirdly, service is available through the Finnish numbering plan . Ficora requested that TeliaSonera develop and implement the ability to identify caller location for emergency services within six months and meet other PATS obligations six months later.
The U.K. regulator Ofcom, in contrast, is going down a different path. Rather than classifying services as PATS when they meet the criteria contained in the EU regulatory framework and fairly strictly applied in the Finnish case, Ofcom proposes to assess broadly and therefore almost by definition more subjectively if a VOIP service is marketed as a replacement for existing PSTN service. Under this model, TeliaSonera’s service might not have qualified as PATS and thus not been subject to the more stringent regulatory terms had the company not marketed its service deliberately as a PSTN substitute. Indeed, taking its clues from these signals, Vonage is deliberately refraining from marketing its service in the U.K. as a substitute for ordinary telephony . Ofcom has recently started a more comprehensive consultation on VOIP in which its simple focus on substitutability is likely to come under scrutiny. In the meantime, by introducing "056" as a special countrywide nongeographic prefix for VOIP services, the U.K. regulator is helping new entrants make the case that they are not offering a direct PSTN substitute as such a service would seek to employ existing geographic numbers and thus freeing them from the more burdensome PATS obligation.
ART, the French regulator, appears to follow the Finnish interpretation of the EU framework. In fact, there is some indication the French might go as far as defining any publicly available service that provides direct, realtime voice communication between fixed and/or mobile users as PATS, even though the Commission explicitly argues that such services could qualify as ECS and should be treated as such if the provider so chooses . Just like Ofcom and the German regulator RegTP, ART has recently launched a public consultation process that is likely to further clarify its position.
It is obvious that VOIP regulation in Europe is still very much in the making. The complicated division of labor between the European Commission as guardian of EU frameworks and the NRAs on the member state level that interpret and implement regulation does not make for straightforward policymaking. Any future VOIP regulation will evolve from the complex back and forth between European and national level policymaking.
It is obvious that VOIP regulation in Europe is still very much in the making. ... Any future VOIP regulation will evolve from the complex back and forth between European and national level policymaking.
As the administrative process unfolds, market players are positioning themselves to shape the classification of VOIP services according to their interests. Initial battle lines are becoming clear. There appears to be a clear distinction between current network owners and those hoping to roll out VOIP services over thirdparty broadband lines. Former monopolists that have dominant positions in DSL markets and cable operators want to gradually introduce VOIP for their customers and are confident they can comply with PATS requirements, such as access to emergency services, wiretapping provision, and network integrity.
What incumbents want to avoid, however, is having to grant thirdparty VOIP providers that fall under the considerably less burdensome ECS regime access to their networks and customers. It is for this reason that they advocate objective criteria to distinguish PATS and ECS, qualityofservice obligations for both network owners and thirdparty application providers, and an obligation to ensure emergency service if VOIP is employed as a fullfledged PSTN substitute. In several member states, the call for objective distinctions appears to resonate with regulators.
In sum, recent European developments contain two obvious points of concern with potentially farreaching implications. The first is that the European Commission’s laudable goal of letting operators choose their regulatory classification is being undermined as regulators search for objective criteria in order to become more prescriptive. Secondly, regulators on the member state level are beginning to diverge in the way they define and apply objective criteria for classification of VOIP services under the EU framework. Put the two trends together and you have a considerable risk that dissimilar regulation across EU member states will fragment the European VOIP market.
The politics of regulatory classification
Both the EU and the United States have taken early steps to fit VOIP into existing regulatory classifications, a course that is more advanced and seems somewhat more orderly in the European case. Yet, politics has inevitably intruded, with important implications for the future course of VOIP deployment.
The FCC’s decision to settle jurisdiction first and substance later is, at best, curious. The European system offers prospective guidance on critical questions like interconnection, access to emergency services, and network reliability. But the FCC has ousted state regulation without explaining what precisely is to replace it. Consider just one example. Suppose that a provider of broadband services in the United States were to deploy its own VOIP service and, simultaneously, either block access to competing VOIP applications, degrade the quality of their service or refuse to exchange traffic with them. With VOIP services within the exclusive jurisdiction of the federal government, what is the federal rule that either permits or limits such practices? At present, none exists. Yet, when, in February 2005, a VOIP provider asserted that a small telephone company was attempting to block its service, the FCC was quick to enter into a consent decree that guaranteed VOIP access . Even so, the FCC chose to act without establishing any general interconnection or openness principles. Indeed, the thenFCC Chair celebrated the agency’s casebycase approach, on the ground that "the surest way to preserve ‘Net Freedom’ is to handle these issues in an enforcement context where hypothetical worriers give way to concrete facts and as we have shown today real solutions " . This disavowal of a rulesbased approach that provides clear guidance to industry players runs the risk of increasing inefficiency in the system unnecessarily.
Given the geography and business realities of Europe, there is no reason why a VOIP transmission from Paris to Brussels should be considered "international" while a transmission from New York to Los Angeles should be considered "domestic."
The European approach also carries with it substantial risk. Because the European Commission retains the authority within Europe to create harmonized regulatory frameworks and to coordinate implementation among the NRAs, the allocation of regulatory authority is not quite as sharp as it first appears. Moreover, over the longterm, the allocation of responsibilities between the NRAs and the EC could fragment the market for VOIP services in Europe. The existence of separate national rules threatens to increase the cost of compliance to the detriment of the marketplace as a whole and to smaller nations in particular. Given the geography and business realities of Europe, there is no reason why a VOIP transmission from Paris to Brussels should be considered "international" while a transmission from New York to Los Angeles should be considered "domestic."
The struggle to classify
The U.S. system has one large disadvantage when compared to the EU approach. As a matter of history, the circuitswitched telephone network has been asked to support a number of social and political goals that are separate from the operation of the networks themselves. The most important is the universal service system; the most unjustifiable is the continuing application of a federal excise tax that was originally enacted in order to raise funds for the SpanishAmerican War . The revenue base for this system rests upon a simple proposition that consumers have no close substitute for the use of the landbased, wireline, circuitswitched, telephone system. Indeed, to the extent that consumers substitute wireless service for traditional landlines, taxing authorities have attempted to "equalize" the burden between the two services .
In a world in which federal, state, and local tax revenues and support for universal service are networkcentric, protection of that network from technological arbitrage is, at least in the short term, an appealing policy for any regulator. And this combined legal/political dilemma may explain why the FCC has not proceeded more vigorously on the creation of an overarching framework in which companies can know in advance the regulatory structure under which their VOIP activities will be measured. In fact, it has taken the FCC an extraordinarily long time to travel even this far. In 1998, the FCC sent to Congress the socalled Stevens Report (named after the longtime Senator from Alaska Ted Stevens) that recognized the importance of offering a regulatory classification for VOIP services. Sadly, however, the report offered agonized ambiguity in place of clear guidance. It took six years before the FCC offered definitive (if limited) guidance in the pulver and AT&T decisions. And, although the agency launched its rulemaking process in early 2004,  the November 2004 Vonage Order went out of its way not to decide the question of regulatory classification. As we have seen, even the FCC’s most recent enforcement action fails to establish any general rule governing VOIP access to lastmile connectivity.
By contrast, the EU has taken a giant step forward by abolishing the "stovepipe" view of regulation that links regulation to underlying network technologies and that characterizes the 1996 U.S. Telecom Act. This is a major step forward because it is, at bottom, accepting of technological change instead of being structurally opposed to it. The European approach thus (1) frees companies from seeking countrybycountry authorization to operate; (2) establishes a neutral right of interconnection; (3) and establishes categories of communications services that are not grounded in network design. As discussed below, the categories themselves are not free from doubt, but the fundamental advantage here belongs to the European approach.
That said, the problem of regulatory definition has not been totally eliminated by the European approach. The distinction in Europe between "Electronic Communications Service" and "Publicly Available Telecommunications Service" was established to enable providers to opt for lighter regulatory treatment and to match benefit and burden. But, in fact, as VOIP services have entered the marketplace, some incumbent European providers have pressed regulators to require VOIP providers to be regulated as PATS without regard to their wishes.
In this context, the question of "substitutability" has arisen as well and there are signs of emerging differences of approach among European regulators. The U.K. regulator Ofcom has begun to ask broadly whether VOIP services are marketed as replacements for existing PSTN service rather than focusing more narrowly on the technological attributes of the service. Such an approach could be justified by service providers’ own product marketing. To take a U.S example, the Vonage Web site prominently exclaims that "Using an existing highspeed Internet connection, Vonage technology enables anyone to make and receive phone calls worldwide with a touchtone telephone" . Indeed, the recent FCC E911 Order on services (completely justifiable as a matter of public safety) employs a new definition of "interconnected VoIP service" that seems to be directed precisely at whether VOIP is acting as a substitute for "regular" telephony.
Ofcom’s thinking and a focus on marketing statements means that a "commonsense" approach threatens to supplant regulatory classifications. Although the U.S. regulatory classifications distinguishing information from telecommunications services are, in our view, fatally flawed, the trend in Europe towards classification applied regardless of a provider’s wishes, may be no more sensible. For example, concluding that VOIP providers must be required to meet qualityofservice requirements because they market a product that is "substitutable" for plain old telephone service would seem to miss the point, as some customers might specifically opt for VOIP to get cheaper service that they know comes with a lower quality. In other words, overreliance on the notion of "substitutability" may actually lessen choice and product innovation in the marketplace. It is noteworthy that Ofcom’s mere pondering of regulation based "substitutability" is already showing effects in the marketplace. Vonage in the U.K., in clear contrast to its abovecited U.S. marketing, is deliberately marketing its service as a supplement to existing PSTN rather than a substitute, even though customers are of course free to cancel their ordinary PSTN service and rely just on Vonage .
To put the issue of "substitutability" into broader perspective, consider just for a moment the manner in which it is applied in European antitrust law. The European Commission has explained that the way to assess the scope of a product market is to examine whether a small, permanent increase in price for Product A would lead consumers to switch to Product B. Thus it explains:"A practical example of this test can be provided by its application to a merger of, for instance, soft drink bottlers. An issue to examine in such a case would be to decide whether different flavours of soft drinks belong to the same market. In practice, the question to address would be if consumers of flavour A would switch to other flavours when confronted with a permanent price increase of 5% to 10% for flavour A. If a sufficient number of consumers would switch to, say, flavour B, to such an extent that the price increase for flavour A would not be profitable due to the resulting loss of sales, then the market would comprise at least flavours A and B. The process would have to be extended in addition to other available flavours until a set of products is identified for which a price rise would not induce a sufficient substitution in demand." 
But here’s the point. The competitionpolicy analysis noted above does not require that product A and product B taste exactly the same product A might be cherryflavored and product B might offer an orangey bouquet. It’s just that market analysis shows that existing cherry lovers might prefer to switch to orange rather than pay some amount more for cherry.
In the regulatory context, however, the analysis of "substitutability" serves a very different purpose, which is to threaten the erasure of product differences. Imagine if a cherryflavored competitor asked a regulator to force the orangeflavored provider to change its flavor merely because the two drinks occupy the same product market. Just because products are similar, they do not have to be identical.
As the soda example shows, the application of a "substitutability" test for purposes of regulation may force VOIP to take on the characteristics of PSTN telephone service. So, for example, under the European regulatory scheme, a number is portable to a VOIP provider and a directoryassistance listing is available only if it complies with all the requirements that define PATS service. The problem with this is that consumers may want the ability to choose just those characteristics that regulation would erase. They may want number portability to reduce switching costs but may be content with lower service quality because they are price sensitive or conclude that current quality requirements are excessive. Or perhaps consumers think that the ability to be listed in a telephone directory is separate from obligations, as under the EU standards, of ensuring against network collapse.
The purpose and politics of classification
In the eyes of most regulators and industry observers, correctly categorizing VOIP provides a shortcut through regulatory uncertainty. Yet precisely this is the problem with classification. As policymakers almost reflexively ask how a new technology fits into existing categories, the underlying political and social objectives of regulation can get lost. In the U.S. for example, the distinction between basic and advanced services has its origins in the antitrust battle against AT&T in the 1970s and 1980s and is strongly characterized by public policy objectives of the time. The EU, in contrast, drew up its regulatory categories after the onset of the Internet age and thus emphasized technological neutrality and future applications. Yet even here, regulation clearly reflects the political context in which it was formulated. In the European case, the overarching interest was to break the dominant position of former monopolists, particularly in the voice market, and to introduce greater competition into the broadband market. And yet, we have seen in the advocacy of those dominant players, a desire to use even the new regulatory categories in a way that will protect existing market share.
Is government assuming a set of product attributes for voice service that is not necessary and that, therefore, acts as an impediment to consumer choice and VOIP adoption?
In short, while efforts to categorize new VOIP services according to existing regulation have taken center stage, the growing disjuncture between the political objectives reflected in these categories and future policy priorities could break open the debate and throw VOIP into even greater regulatory limbo.
We tend to think of telephone service as both networkcentric and composing a particular bundle of product attributes. Even if, as Europe has done, regulation becomes technologicallyneutral, the question remains: is government assuming a set of product attributes for voice service that is not necessary and that, therefore, acts as an impediment to consumer choice and VOIP adoption? It is very important for regulators not to fall into the trap of erecting inadvertent barriers to acceptance or entry by failing to ask whether all the things that we have traditionally considered to be a part of telephone service are actually required in a world of competing kinds of voice service.
The question is particularly important for an emergent technology. The best path for new technologies entering the marketplace may be to offer an alternative not a direct substitution for an existing product or service . But regulation that forces VOIP to act just like an incumbent’s service can threaten its ability to differentiate and employ any particular advantages it enjoys. Indeed, the course of emerging technologies like instant messaging and email might have been very different if they had been viewed, at the outset, as having the potential to compete directly with existing, but seemingly distinct, communications capabilities such as traditional voice service.
Propelled by physics, the future of VOIP may be shaped more by politics. As we have seen, the different approaches of the EU and the U.S. have not constructed any sort of "neutral" zone in which issues of VOIP deployment can be adjudged only on their technical merits. In the U.S., the history of linking social and economic policies to a networkcentric view of the world has caused inevitable confusion as services become increasingly applicationcentric. And recent steps to accommodate publicpolicy goals to IPvoice services have conspicuously failed to address the large questions of regulatory classification. In the EU, the implementation of forwardlooking, technologicallyneutral classifications has not rendered the application of regulatory discretion immune from political advocacy by dominant carriers.
Propelled by physics, the future of VOIP may be shaped more by politics.
The EU approach delinking social and economic issues from the operations of particular networks is clearly preferable. In such a world, the merits of social and economic policies will be more visible to the body politic simply because they cannot be hidden within the opaque operation of incumbent network providers. And transparency will allow such policies as universal service to be more successful because they can be boosted by competition, instead of depending on the maintenance of past market structures.
At the same time that regulators on both sides of the Atlantic begin to ask whether VOIP services are "substitutes" for existing services, it is very important not to assume that consumers will want what they have always received. There is a natural tendency to assume that "telephony" composes a specified set of product attributes but that assumption must be rigorously examined and reexamined as technology and consumer expectations evolve. The risk, of course, is that new forms of stovepipes will emerge to replace the old ones.
VOIP is an application newlyavailable for mass audiences and there is likely to be great dynamic change in the markets as it is adopted. We certainly do not yet know how precisely copperbased circuit networks will continue to be used, how nomadic the use of VOIP devices will become, or the extent to which consumers and businesses will fully adopt the ability to integrate voice, video, and data services.
Governments can take two attitudes towards this uncertainty. They can move cautiously, trying to exempt VOIP from previous regulation on the ground that it is a nascent technology or, even when they rule more broadly, continue to leave great uncertainty in their wake. That has been the attitude of the United States government since at least 1998. The failure to act decisively does, of course, guard against potential error.
We believe, however, that the deadweight costs of such recalcitrance outweigh its benefits. Governments in both Europe and the United States should move aggressively at the federal or, in the European case EU level to establish the rules of the road so that innovators understand their environment and so that competition is driven by underlying value rather than transient arbitrage or regulatory distinctions.
Governments in both Europe and the United States should move aggressively ... to establish the rules of the road so that innovators understand their environment and so that competition is driven by underlying value rather than transient arbitrage or regulatory distinctions.
In that case, how can they learn? First, through international consultation. Europe and the United States (much less the rest of the world, including the nations of Asia that lead the globe in broadband deployment) need not adopt identical rules. They can leave room for experimentation. For example, the approach to emergency services need not be identical perhaps there is a requirement for governmental mandate, perhaps for voluntary (but ubiquitous) industry action, perhaps only for governmentmandated consumer notice. At the same time, some core principles like access to markets will probably require harmonization, as VOIP services move freely across borders.
Second, by understanding the limits of governmental wisdom. In the current climate, inaction is not the best way to express caution (because it leaves the helterskelter structure of outmoded laws in place). It would be better for governments to express limits of omniscience by placing time limits on broad rules, in order to assure that they will be reviewed in five or seven or ten years, rather than eschewing such guidance altogether. Governments should be forced to relearn the marketplace and the trajectory of technology so that they can clearly see which of their prior assumptions have proven to be false and which aspects of the current condition prior rules failed to anticipate. In the world of technology, in particular, it is better to inject some minor uncertainty about the nature of governmental action as it may exist a halfdecade hence rather than to fall victim to the deadweight burden of outmoded reasoning.
Third, and perhaps most importantly, governments need to understand how and why new technologies emerge and why it is important not to stifle them by using approaches designed in different times for different purposes. Evolution is a natural course of market dynamics and differentiation is at the core of evolutionary progress. Thus, governments must be careful not to take actions that inadvertently limit technology and, in the process, constrain their essential, innovative attributes.
VOIP provides a great opportunity to put this fundamental insight into practice. The technology is certain to transform the telecommunications industry. If this prompted governments to rethink and reexamine its own role in the process, the technology has the potential to radically transform the field of telecommunications regulation as well. Were this to happen, VOIP would indeed signal an entirely new era on all fronts.

9. On network openness and competition, see Sallet, 2003. On 3 March 2005, the U.S. Federal Communication Commission (FCC) adopted a consent decree that concluded an investigation into whether a small telephone company had blocked its customers’ ability to use VOIP services. The company agreed to pay a small fine and that it "shall not block ports used for VOIP applications or otherwise prevent customers from using VOIP applications."

10. In the Matter of Vonage Holdings Corp., No. 03211 (12 November 2004) [hereinafter VOIP Order]. The controversy arose when the Minnesota Department of Commerce filed a complaint alleging that Vonage was offering telephone services in Minnesota without first obtaining a "certificate" to provide those services, that it had not followed state procedure for the provision of emergency 911 services and that it had not filed its price list, as telephone companies are required to do. Thereafter, the Minnesota Public Utilities Commission (PUC) ruled that Vonage was required to comply with its rules and statutes governing telephone carriers. Relying on the definition of "information services" discussed below, Vonage claimed not to be providing a "telephone service" within the meaning of state law. Rejecting the Vonage view, the PUC concluded that Vonage’s service was "functionally no different than any other telephone service," noting specifically that Vonage customers use an "ordinary touchtone phone," that Vonage service was "functionally identical" to other telephone services and that the Vonage service "intersects with the public switched telephone network." VOIP Order, at 2 & nn. 3, 93, & 113. Shortly thereafter, a federal court barred the PUC Order from taking effect pending judicial review on the grounds that Vonage was offering an "information service" beyond the power of states to regulate and Vonage sought an FCC Order ruling that federal policy preempted such state regulation.
11. In a press conference following the announcement of the FCC action, the Chief of the FCC’s Wireline Competition Bureau noted the pending status of a series of VOIP proceedings concerning issues that include access charges, lawenforcement requirements and universal service.

13. Beyond the scope of this paper is the FCC doctrine of "forbearance" by which the regulatory authority can, in specified circumstances, determine that regulatory burdens need not apply even though the jurisdictional basis for their application is present. For example, it would be possible for the FCC to find that a service is a "telecommunications service" and then "forbear" from the application of the normal regulatory requirements that accompany that status.

22. And, as noted in footnote 11, the FCC has entered into a consent decree that prohibits a small telephone company from blocking its customers’ access to VOIP services."Interconnected VoIP service. An interconnected Voice over Internet Protocol (VoIP) service is a service that: (1) enables realtime, twoway voice communications; (2) requires a broadband connection from the user’s location; (3) requires Internet protocolcompatible customer premises equipment (CPE); and, (4) permits users generally to receive calls that originate on the public switched telephone network and to terminate calls to the on the public switched telephone network."
28. The framework consists of a Framework Directive (2002/21/EC), the Autorisation Directive (2002/20/EC), the Access Directive (2002/19/EC), the Universal Service Directive (2002/22/EC), and the Privacy Directive (2002/58/EC). Additional provisions that apply are contained in the Competition Directive (2002/77/EC), which was passed the same year.
32. Or, if desired, even apply for the right to offer universal service under the USO category for a given jurisdiction. While no VOIP provider is likely to apply for the role as universal service provider particularly in the infancy of VOIP the Commission explicitly recognizes VOIP providers right to qualify for this role.

38. In 2004, for example, the Maryland Public Service Commission identified the following taxes and fees on local telephone bills (see http://www.psc.state.md.us/psc/Info/brochures/telcharge.htm, accessed 8 April 2005):
Federal Excise Tax of three percent; Federal Local Number Portability fee ($0.23/line); Subscriber Line Charge, which supports the cost of local telephone service, with a cap of $5.61/month for each primary line (and higher fees for nonprimary lines); Federal Universal Service Fund in order to provide affordable telephone service for (1) those who live in areas where the cost of providing phone service is high, particularly rural areas; (2) those with low incomes; (3) schools and libraries; and (4) rural health care providers of $0.53/line (and in addition to a similar universalservice fee that appears on the bill of longdistance carriers); 911 fee for the maintenance of emergency 911 service ($0.25/month from the state plus a separate county fee); Dual Relay Service so that hearing and speechimpaired people would be able to use the telephone system ($0.20/month); Gross Receipts Tax of 2.04 percent tax applied to all basic local service charges, all value added services, calls completed by the operator and message units; State Sales Tax of 5 percent on optional services (such as call waiting); Local Tax, varying by community (for example, 12 percent in the City of Baltimore).
The point is not to question the validity or wisdom of any of these fees, which spring from a variety of motives. The federal excise tax is, for example, entirely unrelated to the telephone system. Universal service funds serve publicpolicy goals that have been paramount in the United States since at least 1913. The Subscriber Line Charge is intended to allow the recovery of the costs of the network. And other fees are intended to recoup costs associated with the telephone networks that are carried out either by government directly, like emergency 911 service, or through the operations of the telephone networks, like dual relay service.
39. For example, wireless customers in Maryland pay the same federal excise tax, federal USF fees, sales tax, local excise tax and 911 fees as on local wireline services. In addition, one county in Maryland has added a fee on wireless service to help fund local schools. See Mackey, 2004.

44. In fact, as Clayton Christensen has powerfully shown, most "disruptive technologies" develop along this trajectory. Precisely because they are sufficiently similar to be adopted as substitutes but different enough to offer new features, these technologies have such a dramatic impact. See Christensen, 2000.
