Taking an informal poll here:
Please respond if you think that having live audio VU meters in the web interface of C-series codecs would be a benefit to you.
Yes, for remote troubleshooting, to see what the local audio level is that the codec is recieving. Could help in determining if the audio is an issue at one of the local or remote ends.
Yes - we have quite a few units with custom A/V integration. The A/V systems are managed by our facilities people and when they fail (as they often do), it would be nice to be able to show that the codec is outputting audio and easily isolate the fault.
