SIP Service

SIP Service
Description
When assigned to support SIP (Session Initiation Protocol), VoIP channels provide protocol conversion between SIP and the iPECS protocol or H.323. This permits the VoIP channel to connect to external SIP networks for call services. 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.
