CA 2172648

Establishing a multimedia telecommunication conference call with reduced bandwidth if not all participants are available to be part of the conference call by telecommunication terminals. When one telecommunication terminal is initiating a conference call, the initiating telecommunication terminal first establishes low speed data links with each of the other telecommunications terminals that are to be part of the conference. When all users of the other telecommunication terminals are ready for the conference, the other telecommunication terminals signal the initiating telecommunication terminal which then adds the necessary bandwidth to the conference call to establish the multimedia telecommunication conference call. Since the conference call is already set up, the initiating telecommunication terminal only has to add the necessary bandwidth to conference call. Each participant in the telecommunication conference call designates when they are ready to have the conference call start. In addition, each participant can choose not to take part in the conference call.
