Agenda
▪ What is SIP Trunking?▪ SIP Trunking Benefits▪ SIP Trunking Deployment Scenarios with Lync ▪ Qualified SIP Trunking Partners
SIP Trunking Overview▪ SIP Trunking enables an enterprise to communicate with internal and external
users over IP, including calls to traditional PSTN networks.▪ Utilizing the SIP protocol provides a platform for future delivery of other real time
communication modalities.

SIP Trunk
SIP Trunking Enables-
Aggregation of Trunks ▪ Combine all voice trunks from many office sites into a few data centers▪ Track and Manage usage using ‘Usage’ portal▪ Quickly add capacity and services on demand (ex. Conferencing)
Aggregation of Access ▪ Reduced number of facilities required▪ No fixed capacity or location requirements▪ Less HW to purchase, maintain, and operate▪ Simpler Integration point to existing IP PBX’s
On-Net Calling▪ Make free calls with users in the same service provider network
SIP Trunking Deployment with Lync
Support▪SIP Forum Website: End-to-End (E2E) support responsibility between Microsoft (MSFT), Service Provider (SP), and Customer are defined by deployment scenario
SBCs (Session Border Controllers)▪SIP Trunking deployment model supports SBC’s at the SP core network or on Premise
E2E Support: Premise Router
▪ Service Provider(SP)/Microsoft (MSFT) provide end to end solution support via UCOIP.▪ Mediation Server and core network SBC interoperate via SIP-TCP/UDP and RTP (G.711).▪ Premise router can transcode G.711 to another codec (ie. G.729) if needed.▪ Lync Server provides network edge access to Lync clients and Lync Server federated networks.
