Need advice for Comfort Noise settings

[mcfarlandrew]

Currently having issues with audio completely cutting out when any audio is picked up by microphone, especially with Music On Hold. I have adjusted the various VCM setting, but have made the issue more prominent. Any advice for best practice would be much appreciated. These are the current settings:

Echo Return Loss (db): 3 db
Nonlinear Processor Mode: Adaptive
NLP Comfort noise Attenuation: -3 db
NLP Comfort Noise Ceiling: -30 db

Turn AGC off on the handset menu

Thank you for your quick response amriddle. However the issue happens when your are on hold with an external line. The only way to clearly hear the music on hold for instance, is to mute the phone that your calling from/to on the outside line(e.g. cell phone, cordless etc.)

What type of phones and what firmware is it on?

BAZINGA!

I'm not insane, my mother had me tested!

Phones are all 9608's currently on release 6.3116

I believe it is the settings in IP Office, not the handsets. Once you take them out of the equation, the issue is still present.

Does the same happen on normal calls?

Hey tlpeter,

It is not happening on normal calls.

Then i think it is normal as i also noticed this recently.
The point is that the phones have a duplex speakerphone but i think it is been done by the software.
On the first releases of the firmware there was no duplex speakerphone.
So i guess this is normal behavior for MOH.

BAZINGA!
