Abstract
A communication system, method, and components are described. Specifically, a communication system having one or more Back-to-Back User Agents (B2BUAs) therein is described. The communication system also includes an RFC 4579 conference focus. Mechanisms are described which enable User Agents (UAs) to subscribe to conference state events and create ad-hoc conferences even though the conference focus is operating in a B2BUA environment.
