Systems and methods for detecting false signals on an outbound call
First Claim
1. A method of detecting false signals on a telephone line, comprising:
- placing an outbound call on a telephone line;
monitoring the telephone line for a detection of a service tone, wherein the service tone is a disconnected tone or a not-in-service tone;
detecting the service tone;
after detecting the service tone, determining, by a processor, that the outbound call is connected; and
upon the detection of a service tone and subsequent determination that the outbound call is connected, processing the outbound call as a false service tone call.

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. Once the additional verification had detected false tones the call can be process as if a connection occurred including routing such calls to an available agent or other handling process customized to handle such calls.

9. A call center for placing outbound calls, comprising:
-
a predictive dialer that places outbound calls on a telephone network; at least one interface that connects the predictive dialer to a telephone network and routes connected outbound calls to a plurality of agents connected to the call center; and at least one processor configured to; detect a service tone on an outbound call, wherein the service tone is a disconnected tone or a not-in-service tone, subsequent to detecting the service tone, determine that the outbound call is connected, and upon the detection of a service tone and subsequent determination that the outbound call is connected, process the outbound call as a false service tone call. - View Dependent Claims (10, 11, 12)
