Technical Summary

This document defines two new mechanisms to allow a SIP User Agent to discover if a SIP conference focus (signaling control point for a conference) supports CCMP, Centralized Conferencing Manipulation Protocol.  One mechanism is a new parameter for the SIP Call-Info header field.  The other mechanism is a new service-uri parameter in the SIP conference event package.  The two methods are not mutually exclusive and can be used individually or together.
