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.

Claims

1. A system for conferencing a plurality of participants in a conference call, comprising:

a bridge having a plurality of conference ports; and

a conference call controller coupled to said bridge, said conference call controller comprising;

means for allocating resources of said bridge to the conference call;

means for simultaneously originating a call to each of said plurality of conference participants, wherein each of said calls is originated via different conference ports; and

means for connecting each of said different conference ports to each other.

2. 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.

3. 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.

4. 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.

5. The system of claim 2, wherein said conference call controller further comprises means for storing conference information in a conference database, wherein said conference information comprises said scheduled time and said required resources.

6. The system of claim 2, wherein said conference call controller further comprises:

means for receiving participant information for the conference call; and

means for storing said participant information in a participant database.

7. The system of claim 1, wherein said means for originating a call to each of said conference participants comprises:

means for allocating an operator console to the conference call and connecting said operator console to a first port on said bridge;

means for originating a call to a conference participant and connecting call audio of said conference participant to a second port on said bridge; and

means for instructing said bridge to connect said first port and said second port so that said operator console can inform said conference participant that the conference call is beginning.

8. The system of claim 7, wherein said conference call controller further comprises the steps of:

means for retrieving participant information from a participant database for the conference call; and

means for allocating ports on said bridge as conference ports.

9. The system of claim 7, wherein said conference call controller further comprises means for connecting an operator console to the conference call to provide operator assistance in response to a request by a conference participant.

10. The system of claim 9, wherein said means for connecting an operator console comprises:

means for receiving a request for operator assistance from a conference participant;

means for connecting said operator console to an available port on said bridge; and

means for connecting said available port to the conference call.

11. The system of claim 10, wherein said conference call controller further comprises means for adding a conference participant, wherein said means for adding a conference participant comprises:

means for capturing call setup information for the additional participant;

means for originating a call to the additional participant via an available port on said bridge; and

means for connecting said available port to the conference call.

12. The system of claim 4, wherein means for querying further comprises means for querying said user using scripted text.

13. The system of claim 5, wherein said conference call controller further comprises means for deleting said conference information from said conference database when the conference call is completed.

14. The system of claim 1, wherein said bridge further comprises a digital signal processor for recognizing and generating tone-based messages.

15. A method for allocating operator consoles during a setup phase of a conference call among a plurality of conference participants, comprising the steps of:

(a) receiving a request from a user to set up the conference call;

(b) identifying available operator consoles;

(c) allocating a plurality of available operator consoles for the conference call setup; and

(d) initiating simultaneous dial-outs to a plurality of prospective conference participants by using said allocated operator consoles.

16. The method of claim 15, wherein the step of identifying comprises the step of polling a network control processor to determine available operator consoles.

17. The method of claim 15, wherein the step of allocating comprises the step of determining a subset of said available operator consoles to be used in the conference call setup.

18. The method of claim 15, further comprising the step of:

(e) tracking the number of prospective conference participants that have not been contacted and continually reallocating available operator consoles until all of the prospective conference participants have been contacted.

19. A system for allocating operator consoles during a setup phase of a conference call among a plurality of conference participants, comprising:

(a) means for receiving a request from a user to set up the conference call;

(b) means for identifying available operator consoles;

(c) means for allocating a plurality of available operator consoles for the conference call setup; and

(d) means for initiating simultaneous dial-outs to a plurality of prospective conference participants by using said allocated operator consoles.

20. The system of claim 19, wherein the means for identifying comprises means for polling a network control processor to determine available operator consoles.

21. The system of claim 19, wherein the means for allocating comprises means for determining a subset of said available operator consoles to be used in the conference call setup.

22. The system of claim 19, further comprising:

(e) means for tracking the number of prospective conference participants that have not been contacted and means for continually reallocating available operator consoles until all of the prospective conference participants have been contacted.
