Abstract: Systems and methods for detecting false signals on a telephone line. The devices provide an additional verification for outbound calls which result in a disconnected or not in service signal that such signals are valid and not false tones being emitted by a device or service employed by the call recipient, The type of additional verification of the outbound call is dependent on the telephone network on which the outbound call is placed. For example, on an analog telephone network a drop in loop current may be detected indicting a connected call which is contrary to the disconnected or not in service signals being received. Such connected signals can be detected on digital networks by monitoring dedicated control data channels or through the use of data received through the use of in-band signaling.

Abstract: The present invention provides a communications system and maintenance system for telephone contact. The present invention is designed to be a stand-alone system used in concert with computers and public telephone switches that are well known in the telephone contact industry. The present invention may, if desired, be integrated into an existing telephone contact system or host program, or, it can be made available as a stand alone product. The communication system enables the telephone service representative to transparently deliver a prerecorded voice file to a party that is consistent in voice tone, quality, energy and pitch. The communication system also provides the telephone service representative with a viewable transcript of the actual voice being transmitted to the party.
