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 bridge for multipoint conferencing among a plurality of endpoints via one or more networks, the bridge comprising: a network interface for exchanging audio data with the plurality of endpoints, at least one endpoint providing audio data containing embedded control data, the control data being substantially humanly inaudible;a control data detection module coupled to said network interface to determine the presence of embedded control data in audio data;an audio unit coupled to said network interface to receive the audio data, to mix the received audio data, and to transmit the mixed audio data; anda bridge control unit coupled to said control data detection module, coupled to said audio unit, and coupled to said network interface, to control operations of the bridge responsive to the presence of embedded control data without determining the content of the embedded control data. 2. The conference bridge of claim 1, wherein the control operation is to provide priority to the endpoint providing the embedded control data. 3. The conference bridge of claim 1, wherein said network interface is configured to work with one or both of an IP network or a PSTN. 4. The conference bridge of claim 3, wherein if the network interface is configured to work with the PSTN, then audio data and control data are provided according to a protocol selected from the group consisting of modem data, ISDN, and analog. 5. A conferencing system comprising: a plurality of endpoints for exchanging audio data, at least one of said plurality of endpoints embedding control data in the audio data;one or more networks providing communication capability for said plurality of endpoints; anda conference bridge for multipoint conferencing, said bridge including: a network interface for exchanging audio data with the plurality of endpoints, at least one endpoint providing audio data containing embedded control data, the control data being substantially humanly inaudible;a control data detection module coupled to said network interface to determine the presence of embedded control data in audio data;an audio unit coupled to said network interface to receive the audio data, to mix the received audio data, and to transmit the mixed audio data; anda bridge control unit coupled to said control data detection module, said audio unit and said network interface to control operations of the bridge responsive to the presence of embedded control data without determining the content of the embedded control data. 6. The conferencing system of claim 5, wherein the control operation is to provide priority to the endpoint providing the embedded control data. 7. The conferencing system of claim 5, wherein said network interface is configured to work with one or both of an IP network or a PSTN. 8. The conferencing system of claim 7, wherein if the network interface is configured to work with the PSTN, then audio data and control data are provided according to a protocol selected from the group consisting of modem data, ISDN, and analog. 9. A method for multipoint conferencing among a plurality of endpoints connected to a multipoint conference bridge via one or more networks, the method comprising the steps of: exchanging audio data between the bridge and the plurality of endpoints, at least one endpoint providing audio data containing embedded control data, the control data being substantially inaudible;determining the presence of embedded control data in audio data;receiving audio data;mixing the received audio data;transmitting the mixed audio data; andcontrolling operations of the bridge responsive to the presence of embedded control data without determining the content of the embedded control data. 10. The method of claim 9, wherein the step of controlling comprises providing priority to the endpoint sending the embedded control data. 11. The method of claim 9, wherein the bridge comprises a network interface configured to work with one or both of an IP network or a PSTN. 12. The method of claim 11, wherein if the network interface is configured to work with the PSTN, then audio data and control data are provided according to a protocol selected from the group consisting of modem data, ISDN, and analog.
