The Centralized Conferencing Manipulation Protocol (CCMP) document
(RFC 6503) defines a way for a client to discover a conference control
server that supports CCMP.  However, it does not define a way for a
client involved in a conference to determine if the conference focus
supports CCMP.  This information would allow a CCMP-enabled client
that joins a conference using SIP to also register for the
Centralized Conferencing (XCON) conference event package and take
advantage of CCMP operations on the conference.

This document describes two mechanisms, depending upon the need of
the User Agent (UA), to address the above limitation.  The first
mechanism uses the Call-Info header field, and the second mechanism
defines a new value for the "purpose" header field parameter in the
<service-uris> element in the SIP conferencing event package.
