Event Interfaces

  • Article

The event (notification) interfaces allow a TAPI 3 application to respond to asynchronous events.

You must call the ITTAPI::put_EventFilter method and set an event filter mask to enable reception of request events. If you do not call ITTAPI::put_EventFilter, your application will not receive any events.

Please see the Events overview for a description of how an application ensures reception of notifications. See the individual interfaces listed in the following table for more information about setting a filter mask for individual event types.
