VIDEO TELECOMMUNICATION ROUTING SYSTEMS AND METHODS

摘要

The present invention involves a system for routing video telecommunication calls received by a central exchange to one of a plurality of video stations connected to the exchange. Each video communication channel occupies two voice-quality telephone channels. Video telecommunication calls are initiated by a video device having preassigned telephone numbers. The video device then calls the central exchange. The routing system contains a telephone switch that connects the first incoming telephone channel to a video station. The ANI of the calling video device is recorded. When the second incoming telephone channel of the same video station is received, its ANI is detected. Because the telephone numbers associated with the calling video device are preassigned, the routing system is able to anticipate the second ANI of the channel which carries the video telecommunication. Upon receiving a call having the second ANI, the routing system then connects this call to the same video station.
