System and method for reducing call interruptions on a telephone

Abstract

The present invention comprises an improved telephone system and method that reduce call interruptions to a telephone, i.e., reduce interruptions caused by a caller placing a call to the telephone. If the no-call feature is enabled and a call is received by the telephone, the telephone answers the incoming telephone call in response to receiving the telephone call. The telephone then plays a message to the caller indicating that no calls are being taken. The telephone does not generate an audible ring signal in response to the telephone call received from the caller. The telephone system further comprises an exemption logic unit for allowing calls placed by certain callers to come through even when the no-call feature is enabled. The user indicates the exception parties to the no-call feature prior to receiving a call from an external party or at a later time. If the caller is determined to be an exception party after a telephone call is received, a ring signal is generated, and the user may then answer the call in a normal fashion. Several methods are used to determine whether the caller is an exception party. In one method, the voice of the caller is analyzed using voice recognition techniques to determine the identity of the caller. Alternatively, a caller is asked to enter a personal identification number. Upon entering the correct identification number, the call is allowed through. A third method of identifying the caller comprises using information obtained from a Caller ID unit.
