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 method for providing call conferencing features in an environment that includes a matrix switch having a matrix switch processor, comprising the steps of:

(1) sending, by a conference call controller to a network control processor, a request to connect an operator console to a first port on a conference bridge, said operator console having only a call audio connection to a port on the matrix switch;

(2) sending, by said network control processor to the matrix switch processor, switch control data instructing the matrix switch processor to connect said operator console to said first port on said conference bridge;

(3) sending, by said conference call controller to said network control processor, a request to originate a telephone call to a prospective participant in a conference call;

(4) sending, by said network control processor to the matrix switch processor, switch control data instructing the matrix switch processor to originate a call to said prospective participant;

(5) connecting, by said matrix switch, said prospective participant to a second port on said conference bridge;

(6) sending, by said conference call controller, instructions to said conference bridge to connect said first port and said second port; and

(7) determining, by said operator console, whether said prospective participant wishes to participate in said conference call.

2. The method of claim 1, further comprising the step of sending operator control data from said network control processor to said operator console, wherein said network control processor provides an interface between the matrix switch and a common channel signaling network.

3. The method of claim 1, further comprising the step of sending participant information from said conference call controller to said operator console.

4. A system for providing call conferencing features in an environment that includes a matrix switch having a matrix switch processor, comprising:

an operator console coupled to the matrix switch, said operator console being connected to a port on the matrix switch; and

a network control processor that instructs the matrix switch to connect said operator console to a first port on a conference bridge, said network control processor further originating a telephone call to a prospective conference participant and instructing the matrix switch to connect said prospective conference participant to a second port on said conference bridge, said first port and said second port being coupled together.

5. The system of claim 4, wherein said network control processor sends operator control data to said operator console via a path independent of the matrix switch, said operator control data being used by said operator console to set up a conference call.

6. The system of claim 4, wherein said network control processor provides an interface between the matrix switch and a common channel signaling network such that said network control processor receives a call data portion corresponding to a call audio portion from said common channel signaling network.

7. The system of claim 4, further comprising a conference call controller, said conference call controller sending participant information to said operator console.

8. The system of claim 7, wherein said conference call controller instructs said network control processor to connect said operator console to said first port of said conference bridge, and to initiate said telephone call to said prospective conference participant.
