Abstract
Abstract A call conferencing system and method includes a conference call controller and a conference bridge. The conference bridge includes a plurality of conference ports, to which conference participant audio is connected. Connection of conference ports in the bridge, bridges together the audio of the participants, thus forming the conference. The call conferencing system receives the initial scheduling request for the conference call, checks resource availability for the scheduled conference date and time, and reserves the required resources for the conference if they are available. To create the conference, conference call controller causes an operator console to be tied to a conference port on the bridge. Conference call controller originates a call to a conference participant via a conference port and ties the participant to the console via the bridge. The console informs the participant of the conference and the conference call controller connects the participant to the conference.
