"Washington, D.C. - The right of consumers to keep the same, familiar phone number when switching to a new telephone company was expanded today by the Federal Communications Commission , in an Order that will further ensure consumers' opportunity to choose a telephone service provider based on quality, price and service.
"The FCC made clear that the obligation to provide local number portability extends to interconnected Voice over Internet Protocol providers and the telecommunications carriers that obtain numbers for them. This action was, in part, a response to numerous complaints by consumers about their inability to port numbers to or from interconnected VoIP providers. The FCC also initiated a Notice of Proposed Rulemaking seeking comment on additional VoIP numbering issues.
"The FCC also clarified in its Order that telephone companies may not obstruct or delay number porting by demanding excess information from the customer's new provider, and specifically concluded that LNP validation for a simple number port should be based on no more than four fields: (1) 10-digit telephone number; (2) customer account number; (3) 5-digit zip code; and (4) pass code, if applicable. In its Notice, the FCC also tentatively concluded that it should require the industry to complete simple ports in 48 hours.

"Facilitate" is defined as the interconnected VoIP providers' affirmative legal obligation to take all steps necessary to initiate or allow a port-in or port-out itself or through the telecommunications carriers, if any, that it relies on to obtain numbering resources, subject to a valid port request, without unreasonable delay or unreasonable procedures that have the effect of delaying or denying porting of the NANP-based telephone number.
(b) An interconnected VoIP provider may not enter into any agreement that would prohibit an end-user customer from porting between interconnected VoIP providers, or to or from a telecommunications carrier.

- Today, providers of interconnected Voice over Internet Protocol services – a popular type of VoIP service which can place calls to and receive calls from the traditional phone network as well as over the Internet – must obtain numbers through traditional telephone companies acting as a middleman. This can raise costs and slow introduction of innovative services, such as high-definition voice.
To determine whether a more streamlined approach is appropriate in the Internet era, the FCC is seeking comment on whether interconnected VoIP providers should have direct access to numbers. In addition, the FCC is seeking comment on easing access for other services that require numbers, such as IP access to emergency services, home security systems, text messaging services, programmable appliances and telematics like hands-free cellular modems in automobiles.
To test a number of technical issues related to the proposals, FCC also launched a limited, six-month trial of direct access to numbers. Vonage and other VoIP providers with pending direct-access waiver petitions at the Commission will be allowed to test direct access for 5% or fewer of the numbers they currently access through intermediaries – phased in over 6 months – and a very limited amount of new numbers. Participants will be required to report monthly on the progress of the trial, and can be required to return the numbers if problems arise. In addition, the FCC granted a limited waiver to TeleCommunication Systems, Inc., which provides access to E911 services for interconnected VoIP providers.
Looking further ahead, the FCC opened a Notice of Inquiry asking about the long-term relationship of numbers to geographic boundaries. The tie between area codes and geographic regions has been weakened by number portability, especially as mobile subscribers move away from the area where they obtained the service but continue using the number. The Inquiry seeks general comment on these trends and whether changes in Commission policies are appropriate.

Order instituting investigation on the Commission's own motion to determine the extent to which the public utility telephone service known as Voice over Internet Protocol should be exempted from regulatory requirements, CA PUC February 11, 2004
Impact of VoIP on Numbering Resources: Federal and state regulators have been successful in slowing the explosive growth of new area codes. Each new area code places additional costs on businesses, adds complexity to the lives of residential consumers, and is inconvenient for all telephone customers. Under Federal Communications Commission (FCC) leadership, California has developed an effective set of rules that ensure that telecommunications providers receive the number they need and makes telecommunications providers efficiently utilize the number they have. VoIP providers currently utilize telephone numbers, but under FCC rules, they do not currently have to comply with protocols under the NANP, thereby potentially undercutting the concerted effort of regulators and carriers subject to the plan to manage scarce numbering resources.
In many ways, the issues presented by VoIP mirror those once presented by wireless providers. Wireless providers, like VoIP providers, offer nationwide service that is portable to the subscriber. Wireless providers, however, register with the California Public Utilities Commission, contribute to state (and federal) universal service programs, pay access charges for interconnection with the PSTN, are required to provide E911 service, and must comply with NANP protocols.
