VeriSign Completes Successful Integration of Private and Public Electronic Numbering (ENUM) Networks in Austria

Successful Integration Enables Carriers to Extend VoIP and Revenue-Generating IP Opportunities beyond Disparate Networks

3GSM Barcelona (13 February 2006) -- VeriSign, Inc. (Nasdaq: VRSN), the leading provider of intelligent infrastructure services for the Internet and telecommunications networks, today announced it has successfully integrated its IP peering solution between Voice over IP (VoIP) service providers and the Austrian Public Electronic Numbering (ENUM) root.  This is one of the first examples of integration between public and private ENUM services and can serve as a template for interconnecting public and private directories to facilitate the growth of Internet Protocol (IP) applications.

ENUM assigns an Internet address to an individual as a single point of communications and allows landline, mobile calls, e-mail and instant messages to be exchanged using one IP number. Public ENUM trials are taking place globally, facilitating commercial convergence between the public switched telephone and VoIP networks.

The public-private integration, which completed compatibility testing last year, gives VeriSign Carrier IP Connect customers access to Austria’s Public ENUM data and eliminates the need to query network databases multiple times to obtain individual contact information.

“Network operators and public policy officials have been waiting for real-world examples of how public ENUM can interoperate with carriers, enterprises and private databases,” said Bill Wolfe, senior vice president, VeriSign Communications Services. “The integration of VeriSign’s carrier directories with Austria’s public ENUM infrastructure can help advance IP use for voice, video and other multimedia needs.”

The Carrier IP Connect service allows Session Initiation Protocol (SIP)-based carriers to access ENUM data even if their networks do not support ENUM. When service providers query the VeriSign service with SIP or ENUM, the technology can look for a private route to the dialed number. If none exists, it will call out to the public ENUM root and return results in a single response.   

“Austria has been a clear leader in creating a commercial public ENUM infrastructure,” said Robert Schischka, general manager of enum.at, the Austrian ENUM registry. “This combined public and private solution is helping Austria build a solid framework for ENUM as the core directory infrastructure for converged services.”

The VeriSign Carrier IP Connect service bridges disparate broadband VoIP networks into a single IP connection. Rather than defaulting external calls to the Public Switch Telephone Network (PSTN), service providers can use the solution to peer with other carriers and enterprises around the world.

It also allows service providers to offer an expanded selection of value-added services such as video and instant messaging and can reduce costs by eliminating per-minute call termination fees. With access to more end points on VeriSign’s global infrastructure, carriers can extend their VoIP reach and be competitively positioned to meet customer needs related to IP technologies.

VeriSign Communications Services enable the delivery of rich and seamless communications, commerce and content interactions. The fully managed, secure and reliable services are designed to help network operators, Internet portals, media companies and retail brands quickly and cost-effectively deliver next-generation voice and data services that can increase usage, loyalty, revenue and competitive advantage.
