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 plays the message after the telephone answers the incoming telephone call. 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 storing a list of exception parties to a no-call feature prior to receiving the telephone call from the caller;

the telephone receiving the telephone call from the caller;

the telephone determining if a no-call feature is enabled;

the telephone determining if the caller is one of the exception parties by comparing the identity of the caller to the list of exception parties;

if the no-call feature is enabled and if the caller is one of the exception parties, the telephone generating a ring signal in response to the telephone call even though the no-call feature is enabled; and

if the no-call feature is enabled and if the caller is not one of the exception parties, the telephone;

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.

2. The method as recited in claim 1, wherein said list of exception parties comprises voice samples of the exception parties, and wherein said determining if the caller is one of the exception parties comprises comparing the caller'"'"'s voice to said voice samples of the exception parties.

3. The method as recited in claim 1, wherein said determining if the caller is one of the exception parties comprises the telephone requesting the caller to enter a personal identification number that identifies the caller.

4. The method as recited in claim 1, wherein said determining if the caller is one of the exception parties comprises utilizing caller ID information from the telephone call.

5. The method as recited in claim 1, further comprising, if the no-call feature is not enabled, the telephone generating the ring signal.

6. The method as recited in claim 1, further comprising, if the no-call feature is enabled and if the caller is not one of the exception parties, 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.

7. The method as recited in claim 6, wherein said warning signal produces a sound shorter in duration and not as loud as said ring signal.

8. 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 storing a list of non-exception parties to a no-call feature prior to receiving the telephone call from the caller;

the telephone receiving the telephone call from the caller;

the telephone determining if a no-call feature is enabled;

the telephone determining if the caller is one of the non-exception parties by comparing the identity of the caller to the list of non-exception parties;

if the no-call feature is enabled and if the caller is not one of the non-exception parties, the telephone generating a ring signal in response to the telephone call even though the no-call feature is enabled; and

if the no-call feature is enabled and if the caller is one of the non-exception parties, the telephone;

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.

9. The method as recited in claim 8, further comprising, if the no-call feature is not enabled, the telephone generating the ring signal.

10. The method as recited in claim 8, further comprising, if the no-call feature is enabled and if the caller is not one of the exception parties, 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.

11. The method as recited in claim 10, wherein said warning signal produces a sound shorter in duration and not as loud as said ring signal.

12. A telephone, comprising:

a microphone for transmitting a user'"'"'s voice to a caller;

a speaker for transmitting the caller'"'"'s voice to the user;

a ringer for sounding a telephone ring to alert the user to incoming calls;

exception logic configured to store a list of exception parties and to determine if incoming calls are from an exception party by comparing the identity of the caller to the list of exception parties;

a no-call logic unit coupled to a telephone line, wherein if a no-call feature is enabled, said no-call logic unit answers all incoming calls that are not from an exception party and plays a no-call message to the caller and disables the ringer from sounding the telephone ring; and

wherein if the no-call feature is not enabled or if an incoming call is from an exception party, the no-call logic does not answer the incoming call and causes the ringer to sound the telephone ring to alert the user so that the user may converse with the caller through the microphone and speaker.

13. The telephone as recited in claim 12, wherein said exception logic is configured to determine if incoming calls are from an exception party according to caller-ID information.

14. The telephone as recited in claim 12, wherein said exception logic is configured to determine if incoming calls are from an exception party by requesting the caller to enter a personal identification number.

15. The telephone as recited in claim 12, wherein said exception logic is configured to determine if incoming calls are from an exception party by comparing the caller'"'"'s voice to previously stored voice samples of exception parties.

16. The telephone as recited in claim 12, further comprising a warning speaker configured to alert the user to incoming calls when the no-call feature is enabled, wherein the warning speaker produces a sound different from the sound produced by said ringer.

17. The telephone as recited in claim 16, wherein said warning speaker produces a sound shorter in duration and not as loud as said ringer.

18. The telephone as recited in claim 12, further comprising a toggle switch for enabling and disabling said no-call feature.

19. The telephone as recited in claim 12, further comprising a keypad, wherein said no-call feature is enabled by entering a code on said keypad.

20. The telephone as recited in claim 12, wherein the telephone is a master telephone that answers incoming calls before any other telephone connected on the telephone line.
