Abstract

Method and apparatus for providing an audio conference bridge initiated remote device muting are disclosed. In a preferred embodiment, a conference bridge is configured to detect a remote mute request from a remote Voice over Internet Protocol (VoIP) device, such as a VoIP telephone. Responsive to this request, the conference bridge sends an indication to the remote VoIP device to cease transmitting audio traffic while still transmitting out-of-band DTMF data.

Claims

1. A method for providing audio conference bridge initiated remote device muting, said method comprising:

hosting, by a conference bridge, two-way communication with a first remote device utilizing Voice over Internet Protocol (VoIP) and two-way communication with a second remote device;

detecting, by said conference bridge, a mute request from said first remote device; and

sending a cease transmitting audio command from said conference bridge to said first remote device, which transmitted the mute request,

wherein the conference bridge maintains the two-way communication with the second remote device after sending the indication to the first remote device,

wherein the first remote device is configured to stop transmitting audio traffic based on the cease transmitting audio command,

wherein said first remote device continues to transmit out-of-band traffic while ceasing to transmit audio traffic.

2. The method of claim 1, wherein said out-of-band traffic comprises DTMF data.

3. The method of claim 2, wherein said first remote device comprises a VoIP telephone.

4. The method of claim 2, wherein said second remote device comprises a Plain Old Telephone System (POTS) telephone coupled to said conference bridge through a VoIP gateway.

5. The method of claim 2, wherein said first remote device is coupled to a remote VoIP gateway, and said first remote device is muted through a local VoIP gateway coupled to said remote VoIP gateway through a network.

19. The method of claim 1, wherein the two-way communication with the first remote device occurs at a first bandwidth before sending the cease transmitting audio command and at a second bandwidth after sending the cease transmitting audio command, wherein the first bandwidth exceeds the second bandwidth.

20. The method of claim 1, wherein after the cease transmitting audio command is received, upstream traffic is reduced thereby providing bandwidth savings.

6. An apparatus for providing audio conference bridge initiated remote device muting comprising:

a conference bridge, said conference bridge configured to;

host two-way communication with a first remote device using Voice over Internet Protocol (VoIP) device and two-way communication with a second remote device;

detect a mute request from the first remote device; and

send a command from the conference bridge to said first remote device, which transmitted the mute request,

wherein the command instructs the first remote device to cease transmitting audio traffic while continuing to transmit out-of-band traffic,

wherein the conference bridge maintains the two-way communication with the second remote device after sending the indication to the first remote device.

7. The apparatus of claim 6, wherein the out-of-band traffic includes DTMF data.

8. The apparatus of claim 7, wherein said first remote device comprises a VoIP telephone.

9. The apparatus of claim 7, wherein said second remote device comprises a Plain Old Telephone System (POTS) telephone coupled to said conference bridge through a VoIP gateway.

10. The apparatus of claim 7, wherein said first remote device is coupled to a remote VoIP gateway, and said first remote device is muted through a local VoIP gateway coupled to said remote VoIP gateway through a network.

11. An apparatus for providing audio conference bridge initiated remote device muting comprising:

means for hosting, by a conference bridge, two-way communication with a first remote device including Voice over Internet Protocol (VoIP) and two-way communication with a second remote device;

means for detecting, by said conference bridge, a mute request from the first remote device; and

means for sending, by said conference bridge, an indication to said first remote device, which transmitted the mute request, to cease transmitting audio traffic, wherein the conference bridge maintains the two-way communication with the second remote device after sending the indication to the first remote device,

wherein said first remote device continues to transmit out-of-band traffic while ceasing to transmit audio traffic.

12. The apparatus of claim 11, wherein said out-of-band traffic comprises DTMF data.

13. The apparatus of claim 12, wherein said second remote device comprises a Plain Old Telephone System (POTS) telephone coupled to said conference bridge through a VoIP gateway means.

14. The apparatus of claim 12, wherein said first remote device is coupled to a remote VoIP gateway means, and said first remote device is muted through a local VoIP gateway means coupled to said remote VoIP gateway means through a network.

15. A non-transitory_program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method for providing audio conference bridge initiated remote device muting, said method comprising:

hosting, by a conference bridge, two-way communication with a first remote Voice over Internet Protocol (VoIP) device and two-way communication with a second remote VoIP device;

detecting, by said conference bridge, a mute request from the first remote VoIP device; and

sending, by said conference bridge, an indication to said first remote VoIP device, which transmitted the mute request, to cease transmitting audio traffic, wherein the conference bridge maintains the two-way communication with the second remote VoIP device after sending the indication to the first remote VoIP device,

wherein said first remote VoIP device continues to transmit out-of-band traffic while ceasing to transmit audio traffic.

16. The method of claim 15, wherein said out-of-band traffic comprises DTMF data.

17. The method of claim 16, wherein said first remote VoIP device comprises a VoIP telephone.

18. The method of claim 16, wherein said first remote VoIP device is coupled to a remote VoIP gateway, and said first remote VoIP device is muted through a local VoIP gateway coupled to said remote VoIP gateway through a network.
