Abstract

An Audio Caller ID service is provided which permits the calling party to speak a real time audio message that can be received and played by the called party'"'"'s Caller ID equipment while his telephone equipment remains in the “on-hook” state. A calling party which has Audio Caller ID (ACID) service would speak a short audio message before dialing the called party. That message is converted to digital form, optionally compressed, and transferred to the called party in a manner similar to conventional Caller ID information. The called party'"'"'s Caller ID equipment operates in the conventional manner, except that the received Audio Caller ID signal is recognized as an audio signal. At the site of the called party, a decoder is provided to convert the digital signal to an analog audio signal, and this analog signal is provided to a speaker, which plays back the calling party'"'"'s audio message.

Claims

1. A method for communicating an audio message between a calling telephone apparatus and a called telephone apparatus while said called telephone apparatus remains in an on-hook state, said calling telephone apparatus and said called telephone apparatus being connected to a telephone system, said method comprising steps of:

receiving a telephone call at a called telephone apparatus from said calling telephone apparatus;

introducing a digitized version of said audio message relating to a call from said calling telephone apparatus over a telephone line to said called telephone apparatus while said telephone line of said called telephone apparatus remains in said on-hook state; and

introducing a signal identifying said calling party during a silent interval following a first ringing signal provided to said called telephone apparatus.

2. The method of claim 1, wherein:

said called telephone apparatus is provided Caller ID information, in addition to said audio message.

3. The method of claim 1 wherein:

said digitized version of said audio message is of sufficient duration to extend beyond a silent interval in which it begins.

4. A method for communicating an audio message from a calling telephone apparatus to called telephone apparatus while said called telephone apparatus remains in an on-hook state, said calling telephone apparatus and said called telephone apparatus being connected to a telephone system, said method comprising the steps of:

receiving a digitized version of said audio message relating to a call from said calling telephone apparatus to said called telephone apparatus over a telephone line during a silent interval following a ringing signal appearing at said called telephone apparatus;

converting said digitized version of said audio message to an acoustic version thereof;

introducing said acoustic version to a speaker to produce an audible version of said audio message; and

receiving a signal identifying said called party during said silent interval following a first ringing signal appearing at said called telephone apparatus.

5. The method of claim 4, wherein:

said called telephone apparatus is provided Caller ID information, in addition to said audio message.

6. The method of claim 4 wherein:

said digitized version of said audio message is of sufficient duration to extend beyond said silent interval in which it begins.

7. Apparatus for communicating an audio message between a calling telephone apparatus and a called telephone apparatus while said called telephone apparatus remains in an on-hook state, said calling telephone apparatus and said called telephone apparatus being connected to a telephone system, comprising:

a silence detector detecting a silent interval following a ringing signal provided to said called telephone apparatus;

a signal injector, responsive to said silence detector, introducing a digitized version of said audio message relating to a call from said calling telephone apparatus to said called telephone apparatus over a telephone line during said detected silent interval; and

a second signal injector introducing a signal identifying said calling party during said silent interval following a first ringing signal provided to said called telephone apparatus.

8. The apparatus of claim 7, wherein:

said called telephone apparatus is provided Caller ID information, in addition to said audio message.

9. The apparatus of claim 7 wherein:

said signal injector introduces a digitized version of said audio message during an interval which begins during said silent interval and extends beyond it.

10. Apparatus for communicating an audio message from a calling telephone apparatus to a called telephone apparatus while said called telephone apparatus remains in an on-hook state, said calling telephone apparatus and said called telephone apparatus being connected to a telephone system, comprising:

a silence detector detecting a silent interval following a second ringing signal provided to said called telephone apparatus;

a receiver, responsive to said silence detector, receiving a digitized version of said audio message relating to a call from a calling telephone to said called telephone apparatus over a telephone line during said detected silent interval;

a digital-to-analog converter converting said digitized version of said audio message to an audio version thereof;

a speaker responsive to said audio version to produce an audible version of said audio message; and

a second receiver responsive to said detection by said silence detector of said silent interval following a first ringing signal.

11. The apparatus of claim 10, wherein:

wherein said second receiver receives, during said silent interval following said first ringing signal, a signal identifying said calling party;

whereby said called telephone apparatus is provided Caller ID information, in addition to said audio message.

12. The apparatus of claim 10 wherein:

said receiver receives said digitized version of said audio signal during an interval which begins during said silent interval and extends beyond it.
