ITToneDetectionEvent interface (tapi3if.h)
The ITToneDetectionEvent interface exposes methods that allow an application to retrieve information about a tone detection event.
The ITToneDetectionEvent interface inherits from the IDispatch interface. ITToneDetectionEvent also has these types of members:
The ITToneDetectionEvent interface has these methods.
The get_AppSpecific method gets the application-defined tag that identifies the tone associated with the tone detection event.
The get_Call method gets a pointer to the call information interface for the call object on which the tone detection event occurred.
The get_CallbackInstance method gets a pointer to the application's callback function that will process the event. (ITToneDetectionEvent.get_CallbackInstance)
The get_TickCount method gets the "tick count" (the number of milliseconds since Windows started) at which the tone was detected.
