  • Patent number: 5654961
    Abstract: In a networked videoconferencing system, a receiver with a number of receiving stations receives calls from a number of different calling stations. To get appropriate bandwidth, two calls are connected at the same time from the calling station to one of the receiving stations. The receiver includes an access switch that uses information from the calling station to pair calls together so that two calls from one calling station are routed to the same receiving station, regardless of the order in which the calls are received by the access switch. The access switch can use one or a combination of routing methods including storing all pairs of incoming numbers in a table and/or by using comparisons of similar numbers.
