B2 offers competitive VoIP service

STOCKHOLM - Cisco Systems announced that its technology will help enable the launch of a new residential telephone service by Bredbandsbolaget (B2), a next-generation Ethernet over fiber broadband provider reaching 220,000 households, which will provide a real alternative to PSTN-based calls in the residential market.

With this end-to-end residential voice service B2 will be offering a competitively priced, fully functional telephony service using VoIP to its existing and new customers outside its established ISP service.

B2 has opted to deliver calls over its Metro Ethernet broadband network using SIP, a flexible communications standard developed for the Internet and providing a simple, stable and cost-effective platform that can be used to integrate new services such as unified messaging in the future.

B2's next-generation Metro Ethernet infrastructure, built around Cisco Catalyst 3500 Switches, Cisco Catalyst 6500 Switches and Cisco 12000 Series Internet RoutersCisco - Cisco 12000 Series Internet Routers, is being augmented to handle voice traffic with a Cisco SIP Proxy Server (CSPS), PGW2200 PSTN Gateway call control and Cisco AS5000 Series Gateways.

The PGW2200 provides the SS7 interface to the Telia's PSTN network and interworks the SS7 circuit switched signalling to the VoIP SIP signalling. The CSPS provides the central call control, routing and location services for users on the network. Customers, meanwhile, will deploy Cisco Analog Telephone Adaptors (ATA) so they can use their existing phones with B2's service.
