4.12.2 SIP Trunk Service
Description
When assigned to support SIP (Session Initiation Protocol), VoIP channels provide protocol
conversion between SIP and the iPECS protocol. This permits the VoIP channel to connect
to external SIP networks for call services. The UCP supports SIP Trunks requiring
registration with or without authentication, as well as provisioned SIP Trunks. In addition, to
the IETF RFC-3261 Session Initiation Protocol draft standard, iPECS VoIP channels support
other SIP related RFCs including:
RFC-2617 HTTP Authentication, Basic & Digest
RFC-3515 Refer Method
RFC-3264 Offer/Answer Model
RFC-3265 SIP Basic Call Flow Examples
RFC-3891 SIP “Replaces” Header
Using the SIP database assignments, the system will register and authenticate with the SIP
proxy server permitting the system to interoperate employing SIP to establish, manage and
terminate real-time voice sessions with external parties.
