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.
Claims17
A method, comprising:
- a Back-to-Back User Agent (B2BUA) receiving an Out-of-Dialog (OOD) message from a User Agent, wherein the OOD message contains a Request URI parameter containing an original conference focus Uniform Resource Identifier (URI) for a conference focus;
- and
- in response to determining that the OOD message contains the Request URI parameter, un-nesting a URI from the Request URI parameter to be a new Request URI and sending a second message to the new Request URI.
A communication system,
- a Back-to-Back User Agent (B2BUA) that is configured to receive an Out-of-Dialog (OOD) message, determine that the OOD message is associated with a conference focus, and in response thereto promote a URI from a contact Uniform Resource Identifier (URI) parameter of the OOD message to be a new Request URI, and send a second message to the new Request URI.
