ABSTRACT:
The system comprises an apparatus for signalling to a party on hold that the hold initiating party is ready to continue conversation. As soon as the hold initiating party places the other party on hold, the party on hold activates the system which causes a pre-recorded message to be transmitted back to the hold initiating party. The pre-recorded message invites the hold initiating party to produce a DTMF signal tone. The DTMF signal activates a tone detector which turns off the message generator and produces an audio and visual signal to alert the party on hold. In this manner the party on hold is free to pursue normal activities until such time as the hold initiating party is ready to talk.
