Quite background white noise on Avaya J169's on internal calls only

[Plug2012]

We have the most pedantic customer who has picked up that when on internal calls on a v11 sp2 ip500 system there is a very quiet white noise you can hear in the background, on external calls its not there. Is there any settings specifically for internal calls I can play with?

Thanks in advance

Try the setting under system/VCM. It's there for a reason though, as it says, when the line is quiet people end up going "are you still there" because it's too quiet...


Nonlinear Processor Mode Default = Adaptive. I
A low level of comfort noise is required on digital lines during periods where there would normally be just silence. This is necessary to reassure users that the call is still connected. These controls allow adjustment of the comfort noise generated by the nonlinear processor (NLP) component of the VCM. The options are:

Adaptive: Adaptive means the comfort noise generated by the NLP will try to match background noise.

Silence: Silence means the NLP will not generate comfort noise at all

Disabled: Nonlinear processing is not applied, in which case some residual echo may be heard.
