Technical Summary

This document defines a framework and requirements for call control
and multi-party usage of SIP. To enable discussion of multi-party
features and applications we define an abstract call model for
describing the media relationships required by many of these. The
model and actions described here are specifically chosen to be
independent of the SIP signaling and/or mixing approach chosen to
actually setup the media relationships. In addition to its dialog
manipulation aspect, this framework includes requirements for
communicating related information and events such as conference and
session state, and session history. This framework also describes
other goals that embody the spirit of SIP applications as used on the
Internet.
