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.
The MMS is responsive to BAS DTMF commands issued by endpoint devices to implement multimedia conferences.
