The ITToneTerminalEvent interface contains methods that retrieve the description of tone terminal events that have occurred.
When the application's implementation of the ITTAPIEventNotification::Event method indicates a TAPI_EVENT equal to TE_TONETERMINAL, the method's pEvent parameter is an IDispatch pointer for the ITToneTerminalEvent interface.
Note You must call the
ITTAPI::put_EventFilter method and set an event filter mask that includes TE_TONETERMINAL to enable reception of tone terminal events. If you do not call ITTAPI::put_EventFilter, your application will not receive any events. For more information, see the
Events overview.
