Clearwire chooses carrier VoIP from Nortel
The network approach is designed to provide an upgrade path to deliver converged fixed and mobile services.
Clearwire’s Internet phone service is currently available in 37 of the company's 46 U.S. markets, but it’s delivered through customers’ existing high-speed Internet access services. The Nortel system will provide end-to-end carrier VoIP infrastructure for Clearwire.
The network that Nortel will build for Clearwire will be based on its own Application Server (AS) 5200 to deliver SIP applications including voice, call management, desktop video calling, collaboration tools and personalization services. The network will also make use of Nortel’s Communication Server 2000 softswitch.
Nortel is also providing VoIP and multimedia solutions to Bell Canada, Rogers Communications, SaskTel, Telus, Verizon, Embarq, Verizon Business, British Telecom, Cable & Wireless and Neuf Cegetel.
Separately, Roberts County Telephone, the local service provider for the rural community of New Effington, S.D., is working to secure a Federal grant that will help underwrite the installation of Nortel’s Communication Server 1500 (CS1500) VoIP softswitch.
Roberts County Telephone and Nortel completed the necessary trials to get the CS 1500 included in the Rural Utilities Service (RUS) List of Materials, which means that other rural American telephone companies can apply for government grants to help purchase Nortel's CS 1500 to upgrade legacy equipment to support IP networks.
