LOS ANGELES, CALIFORNIA--(Marketwire - May 10, 2010) - Attendees at this week's 2010 Cable Show will hear first-hand how Nortel* (OTCBB:NRTLQ) Carrier VoIP and Application Solutions (CVAS) continues to innovate and improve service provider competitive advantage through its industry-leading carrier voice and multimedia product offerings. Today Nortel CVAS unveiled a new centralized SIP engine capability to its state-of-the art market leading Communication Server 2000 (CS 2000) carrier VoIP and multimedia softswitch and Adaptive Application Engine that have been embraced by leading service providers across the globe.

The new centralized SIP engine capability allows service providers to quickly and cost-effectively deliver advanced SIP services and applications to subscribers, including services such as unified communications (UC), web-based UC collaboration, video and multimedia conferencing, hosted call center and other services that improve the way people communicate and conduct business. It allows service providers to deliver SIP and non SIP communication capabilities across the entire network using one Adaptive Application Engine. Competitive standalone application servers can only serve SIP subscribers without support for legacy lines/trunks or services interworking, resulting in isolated service islands with reduced capabilities and requiring significant network integration costs.

In addition, the new capability can be deployed at a single CS 2000 node to extend SIP services to additional CS 2000 nodes in a service provider's network. This helps lower total operational cost for the carrier because it eliminates the need for costly back-office integration required by competitive overlay solutions. The capability also offers full interworking with legacy lines which means that any SIP device can seamlessly interwork with legacy services.

"Nortel CVAS continues to innovate and develop ways to help service providers deliver advanced SIP capabilities to end users quickly and cost-effectively," said Samih Elhage, president, CVAS, Nortel. "Our CS 2000 centralized SIP engine capability accelerates the service provider's time to market and eliminates the need for costly back-office expenses which can cost millions of dollars."

Business subscribers can leverage the solution to migrate to IP at their own pace because it supports IP and TDM lines in the same business group. For example, a call center could have a mix of TDM and IP lines and trunks working together. Residential customers would get full PSTN (including long distance) features over their SIP device, so that they would not see any difference from their current service.

The enhancements are expected to be available in the second half of 2010 and are supported by the latest release of Nortel CVAS' industry-leading [ Communication Server (CS) 2000 ] IP Multimedia softswitch and [ Adaptive Application Engine ] software (CVM release 15/A2E8.0).

Nortel CVAS' CS 2000 centralized SIP engine capability offers several benefits to service providers, including:

• Lower total cost of ownership since no back-office integration is needed to extend SIP functionality across the network.
• Ability to deliver advanced services and ensure compatibility across SIP and non SIP users, while a competitive standalone application server can serve only SIP subscribers.
• No change to translations & routing features, long distance features, customers groups, OAM and billing.
• Service preservation as the capability supports a large number of PSTN Voice and Network services, including toll-free/800 numbers, pre-paid and calling card subscribers
• Flexibility to run in an integrated configuration with Nortel CVAS' CS 2000 and also run in SIP standalone or IMS configurations.

Nortel CVAS' booth (#711) at the [ 2010 Cable Show ]** will feature a variety of innovations that help cable operators offer rich multimedia content, collaboration and communication services to subscribers. Attendees, press or analysts interested in scheduling a meeting should contact Jamie Moody at [ moodyjam@nortel.com ].
