ABSTRACT:
A method and system for call set-up and channel resource allocation between a plurality of parties in a multi-media conference call that consists of receiving notice that a Sender (the initiator of the conference) wants to commence a video conference. At that point, the number of channels required by the proposed call is determined. Subsequently, each requested participant is identified as available, busy, or no answer. If the receiver is available and sufficient channels are available, the call is set-up and the present members of the conference are notified of what channel each should transmit on and what channel(s) to listen to for the other participants. As each receiver is added, the Sender may conference with the present Receiver. If it is decided at this point, that the receiver will not participate in the conference, the call to that receiver may be terminated, and the procedure continues for other receivers until the full conference is set up. Individuals may leave the conference at any time. When the final two participants hang up, the video conference is terminated.
