Assembly: Microsoft.Office.Interop.UccApi (in microsoft.office.interop.uccapi.dll)
These events are used to notify an application of an incoming request to update media or a cancellation of such a request as well as the status of completion of an asynchronous request to update channels maintained by an audio and video session 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.
