ITTAPIEventNotification interface (tapi3if.h)
The ITTAPIEventNotification interface is an outgoing interface that allows an application to control the processing of event information. The application must implement this interface: it must create a COM object that supports this interface, and then register it using the COM standard IConnectionPointContainer and IConnectionPoint interfaces.
The ITTAPIEventNotification::Event method of this interface is called by TAPI in response to an event. Typically, the application implements a set of switch statements that use the value of a TAPI_EVENT enumerator to determine the response to the event.
After registration of this interface, the application calls ITTAPI::put_EventFilter to specify which events it must receive. If this method is not called, the application will not receive any events.
The application may then call ITTAPI::RegisterCallNotifications to notify TAPI of addresses and media types for which the application will accept incoming call sessions.
Please refer to the Event overview for additional information on event handling.
