Abstract

This document defines a framework and the requirements for callcontrol and multi-party usage of the Session Initiation Protocol(SIP). To enable discussion of multi-party features andapplications, we define an abstract call model for describing themedia relationships required by many of these. The model and actionsdescribed here are specifically chosen to be independent of the SIPsignaling and/or mixing approach chosen to actually set up the mediarelationships. In addition to its dialog manipulation aspect, thisframework includes requirements for communicating related informationand events such as conference and session state and session history.This framework also describes other goals that embody the spirit ofSIP applications as used on the Internet such as the definition ofprimitives (not services), invoker and participant orientedprimitives, signaling and mixing model independence, and others.This document is not an Internet Standards Track specification; it ispublished for informational purposes.
