CALLINFOCHANGE_CAUSE

The CALLINFOCHANGE_CAUSE enum is used by the ITCallInfoChangeEvent::get_Cause method to return a description of the type of call information that has changed.

You can retrieve specific information about the change by using the TAPI 3 ITCallInfo interface. TAPI 2 applications use lineGetCallInfo or lineGetCallStatus.
