Session Initiation Protocol (SIP)

The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for sessions.

These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences. SIP can create, modify, and terminate sessions with one or more participants.

The SIP protocol is a member of the ["VOIPProtocolFamily"].
