ITCallHubEvent interface (tapi3if.h)

The ITCallHubEvent interface contains methods that retrieve the description of CallHub events. When the application's implementation of the ITTAPIEventNotification::Event method indicates a TAPI_EVENT equal to TE_CALLHUB, the method's pEvent parameter is an IDispatch pointer for the ITCallHubEvent interface. The methods of this interface can be used to retrieve information concerning the CallHub change that has occurred.

Note  You must call the ITTAPI::put_EventFilter method and set an event filter mask that includes the TE_CALLHUB event to enable reception of CallHub events. If you do not call ITTAPI::put_EventFilter, your application will not receive any events. For more information, see the Events overview.
