Covergence Session Manager latest VoIP-Peerable device certified XConnect Ready

Testing for ENUM Query Compatibility Streamlines Service Providers' Access to XConnect Registry and Participation in Peering Federations

LONDON and MAYNARD, Mass. - March 24, 2009 - XConnect, the leader in Voice over IP (VoIP) and Next Generation Network (NGN) peering, today announced that the Covergence Session Manager has been certified XConnect-Ready. The certification is another step in the development of a global, multi-provider, IP alternative to legacy TDM communication infrastructure.

Produced by Covergence, the leading provider of software solutions that enable organizations to transition from legacy voice to voice as a Web service on their IP network, the Covergence Session Manager (CSM) is a comprehensive package of security, Web-enabling and session management solutions for SIP applications and services marketed to service providers and enterprises.

Certification through the XConnect Ready Partners Program establishes that service providers deploying CSM can query XConnect's ENUM registry for session-routing information. The designation also means the CSM's routing and peering functions work securely and seamlessly for members of XConnect federations. This ensures, in turn, that calls from a CSM-equipped service provider's network can be routed over IP through any XConnect federation member, reaching end points all over the world while bypassing the PSTN.

Avoiding the PSTN delivers key advantages to service providers and their customers. It reduces termination costs while improving call quality. In addition, circumventing PSTN hops permits advanced SIP multimedia services to be carried from end to end of an all-IP call or session.

Reflecting this last benefit, the CSM is designed to help service providers extend their portfolios (and revenue sources) beyond VoIP. It enables them to add innovative, application-integrated functions, such as instant messaging, multimedia conferencing, find-me/follow-me, click-to-dial and presence, as well as to deliver all these features as Web services.

"Having used CSM to add, for example, hosted instant messaging, audio, video, white-boarding and application sharing to their VoIP offering, our service provider customers will be eager to extend the reach of their applications by routing sessions to millions of end points via XConnect federation peers," said Jim Moran, Covergence president and CEO. "They will be able to charge for advanced services and improve their call quality, while still, if they choose, passing on lower international calling costs - an attractive offer."

"Interoperability between the CSM and our ENUM registry and multi-protocol interworking hub will enrich savings and revenue opportunities for Covergence customers belonging to XConnect peering federations," said Eli Katz, XConnect CEO and founder. "Partnering with Covergence brings us closer to universal routing of voice, video and converged IP communications spanning fixed and mobile providers."

The CSM is the latest in a series of devices to successfully undergo XC-Ready interoperability testing. Its certification follows that of other network elements, such as SIP proxies and session border controllers, as well as converged ENUM and SS7/C7 addressing and routing engines. The XConnect Ready Partners Program is designed to create an ecosystem of pretested vendors and solutions to facilitate peering.
