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.

1. A conference endpoint for allowing participation in a conference call via a conference bridge, the conference endpoint comprising: an audio processing unit;a control module communicably coupled to the audio processing unit; anda network interface communicably coupled to the control module;wherein the control module is operable to send control data in combination with audio data to the conference bridge; andwherein the control data comprises an instruction from the conference endpoint that the conference bridge send conference billing information to the conference endpoint. 2. The conference endpoint of claim 1, wherein the conference billing information comprises a real-time cost of conference. 3. The conference endpoint of claim 1, wherein the control data comprises an instruction from the conference endpoint that the conference bridge periodically send conference billing information to the conference endpoint. 4. The conference endpoint of claim 1, wherein the control data comprises an instruction from the conference endpoint that the conference bridge send conference billing information to the conference endpoint upon arrival or departure of any endpoint during a conference. 5. The conference endpoint of claim 1, wherein the control data further comprises payment information sent from the conference endpoint to the conference bridge. 6. The conference endpoint of claim 1, wherein the network interface sends and receives data according to a protocol selected from the group consisting of IP, modem data, ISDN, and analog. 7. The conference endpoint of claim 6, wherein the control data is embedded in the audio data and wherein the control data is substantially humanly inaudible. 8. The conference endpoint of claim 1, wherein the conference endpoint is selected from the group consisting of a computer with a microphone and speaker, an audio communication device without the control module combined with a separate control module, a speakerphone, an IP phone, and a video conferencing unit. 9. The conference endpoint of claim 1, further comprising: a video processing unit communicably coupled to the network interface. 10. A multipoint conferencing system comprising: a plurality of conference endpoints;a multipoint conference bridge; anda communication channel having a communication protocol coupling the plurality of conference endpoints;wherein the multipoint conference bridge connects the plurality of conference endpoints during a conference;wherein each of the plurality of conference endpoints comprises a control module operable to send control data in combination with audio data to the bridge;wherein the control data comprises an instruction from one of the plurality of conference endpoints that the conference bridge send conference billing information to said endpoint; andwherein the conference bridge sends conference billing information to said endpoint. 11. The conferencing system of claim 10, wherein the conference billing information comprises a real-time cost of conference. 12. The conferencing system of claim 10, wherein the control data comprises an instruction from the conference endpoint that the conference bridge periodically send conference billing information to the conference endpoint, and wherein the conference bridge periodically provides conference billing information to the conference endpoint. 13. The conferencing system of claim 10, wherein the control data comprises an instruction from the conference endpoint that the conference bridge send conference billing information to the conference endpoint upon arrival or departure of another endpoint during the conference, and wherein the conference bridge provides conference billing information to the conference endpoint upon arrival or departure of another endpoint during the conference. 14. The conferencing system of claim 10, wherein the communication protocol is selected from the group consisting of IP, modem data, ISDN, and analog. 15. The conferencing system of claim 14, wherein the control data is embedded in the audio data and wherein the control data is substantially humanly inaudible. 16. The conferencing system of claim 10, wherein each of the plurality of conference endpoints is selected from the group consisting of a speakerphone, an IP phone, and a video conferencing unit. 17. A method for obtaining conference billing information during a conference, the method comprising the steps of: combining an audio signal and a control signal;sending a request for conference billing information in the combined audio and control signal from a conference endpoint to a multipoint conference bridge; andreceiving conference billing information from the multipoint conference bridge in the conference endpoint based on a control signal provided in a combined audio and control signal. 18. The method of claim 17, wherein the combined audio and control signal is sent according to a communication protocol selected from the group consisting of IP, modem data, ISDN, and analog. 19. The method of claim 18, wherein the control signal is embedded in the audio signal and wherein the control signal is substantially humanly inaudible. 20. The method of claim 17, further comprising the step of: sending payment information to the bridge. 21. A non-transitory computer-readable medium comprising instructions for obtaining conference billing information during a conference by performing the steps of: combining an audio signal and a control signal;sending a request for conference billing information in the combined audio and control signal from a conference endpoint to a multipoint conference bridge; andreceiving conference billing information from the multipoint conference bridge in the conference endpoint based on a control signal provided in a combined audio and control signal. 22. The non-transitory computer-readable medium of claim 21, wherein the combined audio and control signal is sent according to a communication protocol selected from the group consisting of IP, modem data, ISDN, and analog. 23. The non-transitory computer-readable medium of claim 22, wherein the control signal is embedded in the audio signal and wherein the control signal is substantially humanly inaudible. 24. A multipoint conference bridge comprising: an audio processing unit;a control module communicably coupled to the audio processing unit; anda network interface communicably coupled to the control module;wherein the control module is operable to receive control data in combination with audio data from a conference endpoint;wherein the control data comprises an instruction from the conference endpoint that the conference bridge send conference billing information to the conference endpoint: and,wherein the conference bridge sends conference billing information to the conference endpoint. 25. The conference bridge of claim 24 wherein the conference billing information comprises a real-time cost of conference. 26. The conference bridge of claim 24 wherein the control data comprises an instruction from the conference endpoint that the conference bridge periodically send conference billing information to the conference endpoint. 27. The conference bridge of claim 24 wherein the control data comprises an instruction from the conference endpoint that the conference bridge send conference billing information to the conference endpoint upon arrival or departure of any endpoint during a conference. 28.
