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.

Claim 3
Dependent Claim
84 words
The system of claim 1, wherein said means for allocating comprises: means for receiving schedule information regarding a scheduled time and the number of participants for the conference call; means for determining which of said bridge resources are resources required to handle the conference call, said determination based on said schedule information; means for examining availability of said bridge resources to determine whether said required bridge resources are available at the scheduled time; and means for reserving said required resources for the conference call.
Claim 4
Dependent Claim
62 words
The system of claim 2, wherein said means for examining availability of said bridge resources further comprises means for querying an allocation database to determine whether said required resources are available at said scheduled time, and said means for reserving said required resources comprises means for updating said allocation database to indicate that said required resources are reserved for the conference call.
Claim 5
Dependent Claim
42 words
The system of claim 2, further comprising an operator console coupled to said conference call controller, wherein said operator console comprises: means for querying said user for said schedule information; and means for forwarding said schedule information to said conference call controller.
