Abstract

Certain exemplary embodiments provide a method comprising a plurality of activities, comprising: via a CPE gateway: initiating a communications connection between an audio device coupled to the CPE gateway and a network coupled to the CPE gateway; and negotiating on behalf of the audio device with the network for a parameter associated with processing an audio signal to be transmitted across the network, the audio signal corresponding to a selected audio bandwidth from a plurality of audio bandwidths.

Claims

1. An apparatus comprising:

a CPE gateway coupleable to a network and to an audio device, the CPE gateway adapted to negotiate with the audio device regarding a parameter associated with processing an audio signal to be transmitted across the network, the transmitted audio signal corresponding to a negotiated one of a plurality of audio bandwidths, the plurality of audio bandwidths comprising a first audio bandwidth of approximately 3.1 kHz and a second audio bandwidth of at least approximately 6 kHz.

2. The apparatus of claim 1, further comprising an audio codec.

3. The apparatus of claim 1, further comprising an audio codec adapted to utilize a constant bit rate.

4. The apparatus of claim 1, further comprising an audio codec adapted to utilize a variable bit rate.

5. The apparatus of claim 1, wherein the apparatus is adapted to select an audio codec for processing the audio signal according to the negotiated parameter.

6. The apparatus of claim 1, wherein the audio device comprises a telephone.

7. The apparatus of claim 1, wherein the audio device comprises a microphone.

8. The apparatus of claim 1, wherein the audio device comprises a speaker.

9. The apparatus of claim 1, wherein the audio device comprises an acoustic transducer.

10. The apparatus of claim 1, wherein the audio device comprises an audio player.

11. The apparatus of claim 1, wherein the audio device comprises an audio recorder.

12. The apparatus of claim 1, wherein the network comprises a packet network.

13. The apparatus of claim 1, wherein the network comprises a publicly switched telephone network (PSTN).

14. The apparatus of claim 1, wherein the apparatus comprises the audio device.

15. A method comprising a plurality of activities, comprising:

via a CPE gateway;

initiating a communications connection between an audio device coupled to the CPE gateway and a network coupled to the CPE gateway; and

negotiating on behalf of the audio device with the network for a parameter associated with processing an audio signal to be transmitted across the network, the transmitted audio signal corresponding to a selected audio bandwidth from a plurality of audio bandwidths, the selected audio bandwidth associated with the parameter, the plurality of audio bandwidths comprising a first audio bandwidth of approximately 3.1 kHz and a second audio bandwidth of at least approximately 6 kHz.

16. The method of claim 15, further comprising selecting an audio codec for processing the audio signal according to the negotiated parameter.

17. The method of claim 15, further comprising sampling the audio signal according to the parameter.

18. The method of claim 15, further comprising digitizing the audio signal according to the parameter.

19. The method of claim 15, further comprising formatting the audio signal according to the parameter.

20. The method of claim 15, further comprising compressing the audio signal according to the parameter.

21. The method of claim 15, further comprising providing digitized the audio signal to the network according to the parameter.

22. The method of claim 15, further comprising receiving digitized the audio signal from the network according to the parameter.

23. The method of claim 15, further comprising decompressing the audio signal according to the parameter.

24. The method of claim 15, further comprising converting the audio signal according to the parameter.

25. A machine readable medium storing instructions for activities comprising:

via a CPE gateway;

initiating a communications connection between an audio device coupled to the CPE gateway and a network coupled to the CPE gateway; and

negotiating on behalf of the audio device with the network for a parameter associated with processing an audio signal to be transmitted across the network, the transmitted audio signal corresponding to a selected audio bandwidth from a plurality of audio bandwidths, the selected audio bandwidth associated with the parameter, the plurality of audio bandwidths comprising a first audio bandwidth of approximately 3.1 kHz and a second audio bandwidth of at least approximately 6 kHz.

26. A method comprising a plurality of activities, comprising:

via a CPE gateway;

initiating a communications connection between an audio device coupled to the CPE gateway and a network coupled to the CPE gateway; and

negotiating on behalf of the audio device with the network for a parameter associated with processing an audio signal to be transmitted across the network, the transmitted audio signal corresponding to a selected audio bandwidth from a plurality of audio bandwidths, the selected audio bandwidth associated with the parameter and not larger than an audio bandwidth of the audio device.
