This document defines the framework for Centralized Conferencing.
The framework allows participants using various call signaling
protocols, such as SIP, H.323, Jabber, Q.931 or ISDN User Part
(ISUP), to exchange media in a centralized unicast conference.  The
Centralized Conferencing Framework defines logical entities and
naming conventions.  The framework also outlines a set of
conferencing protocols, which are complementary to the call signaling
protocols, for building advanced conferencing applications.  The
framework binds all the defined components together for the benefit
of builders of conferencing systems.  [STANDARDS TRACK]
