The events are used to notify an application of an addition or removal of a media channel. For an outgoing media session, the events are triggered by the AddChannel or RemoveChannel request made by the local participant. For an incoming session, the events are triggered by the request made by the remote participant. This is a dispinterface. Its members define the event handlers for the events raised by an IUccAudioVideoSessionParticipant object. To catch the events, a UCC API client must implement these event handlers and advise the event source of the implementation if it is interested in receiving the events. To prevent memory leaks, the client should unadvise the events when it is no longer interested in the events.
