Abstract

Disclosed herein are methods, systems, and devices for improved audio, video, and data conferencing. The present invention provides a conferencing system comprising a plurality of endpoints communicating data including audio data and control data according to a communication protocol. A local conference endpoint may control or be controlled by a remote conference endpoint. Data comprising control signals may be exchanged between the local endpoint and remote endpoint via various communication protocols. In other embodiments, the present invention provides for improved bridge architecture for controlling functions of conference endpoints including controlling functions of the bridge.

Claims

1. A method for monitoring a plurality of endpoints participating in a conference call via a conference bridge, the method comprising the steps of:

receiving a control signal embedded in an audio signal from the conference bridge, wherein the control signal is substantially humanly inaudible and comprises information regarding the endpoints currently participating in the conference call; and

,

extracting the control signal from the audio signal.

2. The method of claim 1 wherein the control signal is received according to a communication protocol selected from the group consisting of IP, modem data, ISDN, and analog.

3. The method of claim 1 wherein the step of receiving a control signal is provided periodically.

4. The method of claim 1 wherein the step of receiving a control signal is provided in response to a request from the speakerphone.

5. The method of claim 1 wherein the step of receiving a control signal is provided upon a joining endpoint'"'"'s joining the conference call.

6. The method of claim 1 wherein the step of receiving a control signal is provided upon a leaving endpoint'"'"'s leaving the conference call.

7. A non-transitory, computer-readable medium comprising instructions for monitoring a plurality of endpoints participating in a conference call via a conference bridge by performing the steps of:

receiving a control signal embedded in an audio signal from the conference bridge, wherein the control signal is substantially humanly inaudible and comprises information regarding the endpoints currently participating in the conference call; and

,

extracting the control signal from the audio signal.

8. The non-transitory, computer-readable medium of claim 7 wherein the control signal is received according to a communication protocol selected from the group consisting of IP, modem data, ISDN, and analog.

9. The non-transitory, computer-readable medium of claim 7 wherein the step of receiving a control signal is provided periodically.

10. The non-transitory, computer-readable medium of claim 7 wherein the step of receiving a control signal is provided in response to a request from the speakerphone.

11. The non-transitory, computer-readable medium of claim 7 wherein the step of receiving a control signal is provided upon a joining endpoint'"'"'s joining the conference call.

12. The non-transitory, computer-readable medium of claim 7 wherein the step of receiving a control signal is provided upon a leaving endpoint'"'"'s leaving the conference call.
