Abstract
A teleconferencing/videoconferencing system has (1) a plurality of AV device, each capable of originating and reproducing user related audio and video signals; (2) a plurality of communications ports, each supporting the switch connections of video in, video out, audio in, and audio out; and (3) a communication path arranged for transport of audio and video signals. The system controls communications, over the communications path, between two of the AV devices by creating a first and second call handles, respectively associated with the two AV devices. Each call handle defines a call state (Either active and/or hold), and the AV device's port's switch connections involved in the communication connection. The system also allows a user to remotely put another caller on hold or remotely disconnect another caller.
