Three-way call detection and response system
First Claim
1. A system for analyzing a plurality of data streams including, at least, digitized ongoing telephone conversations, for a three-way telephone call placement attempt, comprising:
- monitoring means for selectively monitoring individual data streams of a plurality of digitized ongoing telephone conversations, at least one of which is desired monitored, without substantial interruption of said data streams;
comparison means for comparing each of said data streams with predetermined indicia determining if a specific monitored data stream includes an attempt at a three-way telephone call placement; and
response means for actively responding to a specific monitored data stream having a positive comparison indicating a three-way telephone call attempt has occurred.

Abstract
A three-way call detection and response system comprising, in accordance with a preferred embodiment, a three-way call detector coupled non-intrusively, by a bridge repeater, to a communication path carrying digital signals between originator and recipient end office telecommunication switches. The three-way call detector includes an interface and a digital signal processor electrically connected to the bridge repeater for receipt of digital signals from the communication path. The three-way call detector also includes a local controller which interacts with the interface, a digital signal processor, and a remote controller. The remote controller executes a plurality of software programs which control operation of the system. In accordance with a preferred method, the three-way call detection and response system monitors the communication path for indicia representative of a three-way call signature and, hence, an attempted three-way call placement. Upon identifying a suspected three-way call signature, the system examines the digital signals to determine the spectral characteristics of a suspected release pulse of the suspected three-way call signature. Using pattern recognition techniques to compare the spectral characteristics of the suspected release pulse with the spectral characteristics of known, reference release pulses, the system determines whether or not the release pulse is substantially similar to the release pulse of an actual three-way call signature. If so, and after also identifying first and second periods of silence about the release pulse, the system responds to the detection, for example, by disconnecting the telephone call, playing a recording over the communication path, or creating a record of the attempted three-way call placement.

- 16. A digital comparison process for identifying a three-way telephone call placement attempt in one of a plurality of data streams including, at least, digitized ongoing telephone conversations, comprising the steps of monitoring a stream of data including a digitized ongoing telephone conversation, identifying suspected segments of the data stream having the characteristics of a three-way call placement attempt, and comparing the suspected segments to predetermined segments known to be three-way call placement attempts to determine if the data stream includes an attempt at a three-way telephone call placement.
