摘要:
In a telephone system, if the telephone set of a called party is busy or an incoming call is not answered, the called party is unavailable. In this event an incoming call may progress to become intercepted at an attendant position or at a voice features server. A call take back feature permits the called party to be aware of an intercepted call progress so that the called party may retrieve the incoming call by going OFF HOOK and conversing directly with the calling party. A call screening feature is also available. The call screening feature permits the called party to hear the calling party's voice during an intercepted call progress via an audible link provided by the telephone system from the intercepted call. The called party may, at his discretion, retrieve the incoming call from the intercepted call progress by going OFF HOOK and conversing directly with the calling party.
