  • Patent number: 5883945
    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.
