Country Code 1 ENUM LLC Enables Next Generation Services With Launch of Extensible ENUM Registry Service

CC1 ENUM LLC, With Members Including Verizon and AT&T, Partners With Telcordia to Enable Cost-Effective, Reliable IP Interconnection for Communication Service Providers, Mobile Content Providers

DENVER, CO and PISCATAWAY, NJ--(Marketwire - February 17, 2009) - With an eye on providing the industry's most flexible infrastructure for interconnection of Next Generation services, the County Code 1 (CC1) ENUM LLC has selected Telcordia to build and manage a highly scalable and extensible Registry service to enable inter-carrier VoIP, multimedia, SMS, MMS and other applications among communication service providers.

The new service will enable both domestic and international communication service providers to leverage IP-based interconnect capabilities to increase the breadth and reach of their service offerings. It will also help ensure the efficient and secure delivery of their traffic while allowing service providers and content providers to continue using telephone numbers as the primary means for subscriber identification.

The CC1 ENUM LLC promotes the development of ENUM (Electronic Numbering) technology and sets the stage to accelerate the rollout and adoption of next generation advanced communications services. Enabled by ENUM technology, the interconnection capability allows participating operators and mobile content providers around the globe, to map subscribers' phone numbers to IP gateways thereby allowing IP-based services to be delivered across providers' networks in a secure, reliable and cost efficient manner.

"The flexible, scalable architecture of Telcordia's interconnection suite enables the delivery of next-generation applications and services across partner networks by providing accurate and authoritative user, provider and network information," said Richard Jacowleff, President, Interconnection Solutions, Telcordia. "The CC1 ENUM LLC understood the critical need for accurate routing of IP-based traffic and content, and proactively set in motion an interconnection solution with Telcordia to establish an authoritative routing Registry for Country Code 1 that supports next generation services."

"We are extremely excited about spearheading a service that will help move the industry forward towards a truly converged network environment," said Jim Baskin, Chairman of the ENUM LLC. "We also believe that other service providers will join companies like AT&T and Verizon and become members of the CC1 Provider ENUM community resulting in the accelerated deployment of new IP-based services. We are pleased to be partnering with Telcordia Technologies. We selected them not only for their robust technology but also based on their proven track record of operating large-scale interconnection solutions."

"This agreement represents an important step for the industry as we move towards IP-based interconnection and next generation services," said Steve Lind of AT&T and Vice-Chairman of the ENUM LLC.

Participating service providers pay a nominal fee to access the Registry service for routing IP-based traffic. Without the service, this traffic would have to revert to a TDM-based network and lose the cost efficiencies of IP communications. Operators can choose between different interconnect modalities (e.g. bilateral, multilateral, etc.) and offer new IP-based services while retaining subscriber telephone numbers as the basis for ubiquitous addressing.

The CC1 ENUM LLC Provider ENUM Registry Service, powered by Telcordia, is planned for launch in the second half of 2009. Once fully deployed, this service is expected to manage interconnection data for over 500 million telephone numbers in North America. As part of its implementation of Provider ENUM, the LLC plans to form a User Group of participating service providers.


The CC1 ENUM LLC was created to implement electronic numbering (ENUM) in North America and, more specifically, in the United States. Its work has included both End-user and Provider ENUM Projects. It has sponsored industry trials in both areas that were conducted during the 2006-2007 period. ENUM describes how the Domain Name System (DNS) can be used for identifying available services associated with individual telephone numbers. Through transformation of telephone numbers into DNS names and with the use of existing DNS services with Provider ENUM, service providers can look up and find the interconnection services that are available for a specific telephone number in a decentralized way with distributed management of the different levels in the lookup process.
