3. SIP Trunk Interworking: How the SIP Forum is Improving Interoperability between SIP-PBXs and Serv
Presented by David Hancock and John Berg, CableLabs, and James Swan, UNH-IOL.
Interworking issues continue to be an obstacle to achieving scale on SIP Trunk deployments. Due to variances in the SIP profiles supported by different SIP Trunk products, Service Providers and vendors are forced to spend significant time and people resources to identify and resolve interworking issues for each new SIP-PBX/SSP-network combination. The SIP Forum has been actively working on multiple fronts to resolve this interworking roadblock, and to move the rollout of SIP Trunking service toward more of a plug-and-play deployment model.
This session provides a status update on two important SIP Forum initiatives in this area:
1. The SIPconnect 1.1 Recommendation: This recommendation defines a SIP profile for the SIP Trunk interface between a SIP-PBX and Service Provider network. It defines procedures to resolve common interworking issues at the SIP Trunk interface for capabilities such as security, PBX registration, and call features.
2. The SIPconnect 1.1 Interop and Compliance Program: The focus of this program is to encourage the adoption of SIPconnect 1.1 through a series on interop events, and ultimately to develop a rigorous test-platform-based compliance program that will enable vendors to indicate product compliance with SIPconnect 1.1.
