NEW ORLEANS, May 4, 2004 (BUSINESS WIRE) -- Nortel Networks (NT) (CA:NT) today announced that it has been selected by Charter Communications, Inc. (CHTR) to expand voice over Internet Protocol (VoIP) service offerings in Charter's Midwest and Great Lakes operating divisions using Nortel Networks cable VoIP solution featuring Succession Communication Server (CS) 2000-Compact softswitches. This selection, which extends a relationship announced in December 2002, is subject to execution of a definitive agreement.

"We've rebuilt and upgraded our infrastructure to deliver advanced products and services including voice over IP," said Wayne Davis, senior vice president, Engineering and Technical Operations, Charter. "As such, Nortel Networks has played a strategic role in our packet network transformation, delivering a cable voice over IP solution that is very robust and mature. Their extensive knowledge of cable telephony, together with a strong background in services and professional support, has enabled us to aggressively enter and compete in the telephony market."

As part of its overall expansion, Davis also said Charter intends to deploy Nortel Networks Multimedia Communication Server (MCS) 5200 in a 2004 market trial, giving both residential and business customers access to multimedia services independent of location. The new Charter VoIP architecture will include the capability to communicate between a Session Initiation Protocol (SIP) server and a PacketCable(TM) qualified Call Management Server (CMS), effectively bringing the rich world of SIP-based features to a PacketCable environment.

"Nortel Networks is fundamentally changing interpersonal communications across all markets," said Dan Mondor, general manager, Global Cable Solutions, Nortel Networks. "We have generated critical momentum in the cable market and continue to focus efforts on delivering carrier-grade cable solutions that enable providers like Charter to pave the way for new integrated video, voice, and data services. Charter continues to be a leader in cable IP telephony and this addition to their services portfolio will help them to drive increased revenue opportunities."

To speed time to market and ensure carrier grade service for its customers, Charter will use Nortel Networks professional services to support the planning and deployment of the VoIP solution.

In September 2002, Charter deployed the first commercially available cable VoIP service in North America using Nortel Networks equipment, and has experienced virtually no downtime on the softswitch since launch.

For the entire year and fourth quarter of 2003, Nortel Networks ranked #1 in the global markets for voice over IP ports shipped and in global softswitch revenue, according to Synergy Research Group and In-Stat/MDR. Nortel Networks has a proven portfolio of products and services for packet voice and multimedia services. Nortel Networks is providing Succession VoIP solutions to leading operators, including Cox Communications, Sprint, MCI, TeleCable, Hong Kong Broadband Network, Verizon Communications, Bell Canada, Cable & Wireless Cayman Islands, China Netcom and China Railcom.
