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.

Claims

1. A method for reducing call interruptions on a telephone, wherein the call interruptions are produced by a caller placing a call to the telephone, the method comprising:

the telephone receiving the telephone call from the caller;

the telephone determining if a nocall feature is enabled;

if the no-call feature is not enabled, the telephone generating a ring signal; and

if the no-call feature is enabled, the telephone;

generating a warning signal to alert a user that an in-coming call has been received while the no-call feature is enabled, wherein said warning signal produces a sound different from said ring signal;

answering said telephone call prior to the telephone ringing; and

playing a message to the caller indicating that no calls are being taken, wherein the telephone plays the message after the telephone answers the telephone call and after said generating a warning signal.

2. The method as recited in claim 1, further comprising, if the no-call feature is enabled, the telephone disconnecting from a telephone line after playing the message to the caller indicating that no calls are being taken, wherein the telephone disconnects without the caller being able to leave a message.

3. The method as recited in claim 1, further comprising receiving user input to the telephone to enable the no-call feature.

4. The method as recited in claim 3, further comprising disabling ring circuitry on the telephone in response to said receiving user input to the telephone to enable the no-call feature, wherein said disabling the ring circuitry occurs prior to said receiving the telephone call the caller.

5. The method as recited in claim 3, wherein said receiving user input to the telephone to enable the no-call feature comprises receiving user input to a telephone keypad of the telephone.

6. The method as recited in claim 3, further comprising enabling the no-call feature to other telephones connected on a same telephone line as the telephone.

7. The method as recited in claim 6, further comprising disabling ringers of the other telephones that are connected the same telephone line.

8. The method as recited in claim 1, wherein said warning signal produces a sound shorter in duration and not as loud as said ring signal.

9. A telephone system, comprising:

a port for coupling to a telephone line for receiving telephone signals;

circuitry for generating a ring signal;

circuitry for generating a warning signal; and

no-call feature logic coupled to the port, to the circuitry for generating a ring signal and to the circuitry for generating a warning signal, wherein said no-call feature logic determines whether a no-call feature is enabled;

wherein said no-call feature logic, in response to a received call and if said no-call feature is enabled;

causes said circuitry for generating a warning signal to generate the warning signal to alert a user that an in-coming call has been received while the no-call feature is enabled;

answers the received call without allowing the circuitry for generating a ring signal to generate a ring signal; and

after said warning signal is generated, plays a message to a caller indicating that no calls are being taken;

wherein said warning signal produces a sound different than said ring signal.

10. The telephone system as recited in claim 9, wherein said no-call feature logic, in response to the received call and if said no-call feature is not enabled, causes said circuitry for generating a ring signal to generate the ring signal.

11. The telephone system as recited in claim 9, wherein said warning signal produces a sound shorter in duration and not as loud as said ring signal.

12. The telephone system as recited in claim 9, wherein said no-call feature logic is configured to receive a first numeric code from a keypad of said telephone system for enabling said no-call feature and a second numeric code from said keypad of said telephone system for disabling said no-call feature.

13. The telephone system as recited in claim 9, further comprising a no-call button for a telephone user to enable and disable said no-call feature.

14. The telephone system as recited in claim 9, further comprising answering machine logic for enabling a caller to leave a message if the no-call feature is enabled.
