发明名称 Anonymous call rejection
摘要 The present invention provides a method, system and device/phone/computer for anonymous call rejection in an Internet Protocol telephony network. The method includes the steps of: determining whether a caller identification ID is available/identifiable for an incoming call; and rejecting the incoming call where the caller ID is unavailable or unidentifiable. The system includes a Caller Identification Unit, for determining whether a caller identification ID is available/identifiable for an incoming call and a Call Rejection Unit, coupled to the Caller Identification Unit, for rejecting the incoming call where the caller ID is unavailable or unidentifiable. A device/phone/computer of the invention provides a caller identification processing/rejecting unit and a transceiver. The caller identification processing/rejecting unit determines whether a caller identification ID is available or identifiable for an incoming call and rejects the incoming call where the caller ID is unavailable or unidentifiable. The transceiver is coupled to the caller identification processing/rejecting unit and is used for transmitting and for receiving calls when the caller ID is available or identifiable.
