Call Object Interfaces
The Call object is created when a call comes into existence. Associated interfaces get and set information concerning the call.
Enumerator and event interfaces are not directly exposed on the Call Object, but are listed here for reference convenience.
The ITCallNotificationEvent, ITCallInfoChangeEvent, ITCallStateEvent, ITCallMediaEvent, and IEnumTerminalClass interfaces are not directly exposed on the Call Object, but are tightly related to it and are listed here for reference convenience.
