Cisco, Verizon to use Genuity's VoIP

Genuity said Wednesday that Cisco Systems and Verizon will be the first companies to use its Black Rocket Voice, a service that provides voice phone calls using VoIP (voice over IP) technology. Genuity uses its own telecommunications network to provide Internet and e-business services such as hosting, Internet access and security to businesses. Cisco will use Black Rocket Voice to power the 35,000 IP phones at 41 company sites in the United States. VoIP splits voice data into many packets, and sends them over the network in separate chunks to their destination, where they are reassembled into a regular voice call. The technology uses bandwidth more efficiently and reduces cost, compared with a traditional circuit-switch call, which delivers voice data in its entirety using a continuous connection.
