/**
 * The CallControlCallObserver reports all events for the CallControlCall,
 * CallControlConnection, and CallControlTerminalConnection objects. Note that
 * this interface does not support any methods. Application which want
 * CallControlCall, CallControlConnection, or CallControlTerminalConnection
 * events should instantiate an object which implements this interface.
 * Because this interface extends the telehpony.CallObserver interface, all
 * events are reported via the <EM>CallObserver.callChangedEvent</EM> method.
 * Therefore, all CallControlCall, CallControlConnection, and
 * CallControlTerminalConnection events must extend the telphony.events.CallEv
 * interface.
 * <p>
 * This interface exists to allow applications to "signal" to the 
 * implementation whether or not they want CallControlCall,
 * CallControlConnection, or CallControlTerminalConnection events delivered
 * to their application. 
 * <p>
