The events are used to notify the application of the operation progress of the asynchronous session call control requests initiated by the local user. This is a dispinterface. Its members define the event handlers for the events raised by an IUccSessionCallControl 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.
