Session Initiation Protocol (SIP) Service
When assigned to support Session Initiation Protocol (SIP), VoIP channels provide protocol
conversion between SIP and H.323. This permits the VoIP channel to connect to external SIP
Networks for call services. In addition, to the IETF RFC-3261 SIP draft standard, System’s
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.
