 * The MediaCallObserver extends the CallObserver interface and

 * <p>
 * This interface does not have any methods. All events for the
 * MediaTerminalConnection object are reported via the callChangedEvent()
 * method on the CallObserver interface. All MediaTerminalConnection events,
 * therefore, extend the core TermConnEv interface (which extends the core
 * CallEv interface.

 * Applications which desire MediaTerminalConnection events implement this
 * interface as a "signal" to the implementation that is wants to be sent
 * events for the MediaTerminalConnection object.
