US 2008/0260133 A1 · System and method for dectecting three-way attempts

Abstract

Disclosed is an improved three-way call detection system and method for use with a telephone management system. Specifically, a three-way call detection system and method for detecting continuous noise indicative of a an attempt to circumvent existing three-way call detection systems and methods. The continuous noise detection system and method may be used in conjunction with any existing three-way call detection system and method, including for example, a system and method that monitors the active communications of the telephone management system for pulses of energy indicative of a three-way call.

Dependent claims

A method for detecting continuous noise indicative of a three-way call circumvention attempt, said method comprising the steps of:

monitoring an audio stream;
detecting when said stream falls below a pre-determined threshold;
detecting when said stream exceeds said pre-determined threshold;
detecting the next occurrence of said stream falling below said pre-determined threshold;
comparing the time elapsed between said stream exceeding said pre-determined threshold and said next occurrence of said stream falling below said pre-determined threshold to a pre-determined maximum allowable period of time indicative of a continuous noise three-way call circumvention attempt.
