Release of a new draft “SIPconnect Interface Specification” provides standards-based direct IP peering between IP PBXs and VoIP service provider networks.
Cbeyond Communications and five other IP telephony vendors, Avaya, BroadSoft, Centrepoint Technologies, Cisco Systems, and Mitel, have developed a draft best practices specification to guide interoperability between IP PBXs and VoIP service provider networks.
The rapid deployment of IP PBXs in businesses and the transition to VoIP by service providers has created an opportunity for direct IP peering between IP PBXs and VoIP-enabled service providers which would lower costs, reduce voice latency, and provide for end-to-end SIP signaling for PSTN termination.
The newly released, publicly available SIPconnect Interface Specification leverages the SIP and other IETF VoIP protocols to provide the consistent, industry standards-based approach to interconnection essential to the future of packet-based communications.
Cbeyond Communications, Avaya, BroadSoft, Centrepoint Technologies, Cisco Systems, and Mitel have all indicated their intention to develop products and services that comply with the new draft specification, to the extent that any of their current product lines do not already do so.
They state that SIPconnect specifies a reference architecture, required protocols and features, and implementation rules necessary for seamless peering. It defines a clear and consistent architecture that enables IP PBX vendors and service providers to rapidly and cost effectively deploy VoIP services. They invite the rest of the industry to join and follow them.
