| Platform SDK: TAPI |
The ITCallNotificationEvent interface contains methods that retrieve the description of call notification events. When the application's implementation of the ITTAPIEventNotification::Event method indicates a TAPI_EVENT equal to TE_CALLNOTIFICATION, the method's pEvent parameter is an IDispatch pointer for the ITCallNotificationEvent interface. The methods of this interface can be used to retrieve information concerning the call notification event that has occurred.
This outgoing interface is registered with the TAPI object to get all information about calls. An application must call the ITTAPI::RegisterCallNotifications method on the TAPI object before registering this interface.
Note You must call the ITTAPI::put_EventFilter method and set an event filter mask that includes the TE_CALLNOTIFICATION event to enable reception of call notification events. If you do not call ITTAPI::put_EventFilter, your application will not receive any events. For more information, see the Events overview.
