Abstract

Techniques are disclosed for controlling the communication of multimedia electronic signals representing audio, video, and/or data. These techniques operate in conjunction with a system including a network and a plurality of endpoint devices connected to the network. A novel MMS is coupled to the network and is equipped to utilize the network such that multimedia signals may be exchanged among a plurality of endpoint devices, thereby providing a multimedia conference. A Multi-Media Server (MMS) provides a multimedia conference independently, such that the reservation system utilized by existing multimedia conferencing system is no longer required. The conference is initiated by a multimedia endpoint that is equipped with a user interface device for encoding user input as BAS signals.
The MMS is responsive to BAS DTMF commands issued by endpoint devices to implement multimedia conferences.
