ABSTRACT:
A technique is disclosed that enables one or more telecommunications endpoints to subscribe to a conferencing system and to be notified of one or more conferencing events. As part of the conferencing system of the illustrative embodiment, a conference invitation server maintains information on all of the conferences that are scheduled to occur on the conferencing system, including (i) the addresses of the identified participants for each call and (ii) the conference identifier that the server generates for each call. When a conference call is going to begin, the server sends out notifications to all endpoints that are subscribed to the conference. If there are participants who are not subscribed to the conference, then alternative mechanisms for notifying participants can be used. Each subscribed endpoint then transmits a request to join the conference—either via user interaction or automatically—providing the conference identifier as part of the join request.
