This event fires when the call is deallocated by ThbTapiLine. This happens when the call object is freed and it's handle is dallocated. After this event has fired, the call object is no longer available and all pointers to it should be cleared.

By default ThbTapiLine deallocates idle calls automatically after a delay set in the property ThbTapiLine.Options.AutoFreeIdleCalls.
