Outgoing voice low volume - PRI

frontier
Level 1
Level 1

Hi there,

I am having an issue with low volume of voice going out, incoming is fine.

I have a 2801 with PRI and a couple of 7911 phones.

I have tried the "output attenuation" command under the voice port, but it did not make any diference, even between -6 or 14. On the other way, "input gain" worked fine.

Could it be the provider (BT) that is normalising the signal?

Hi, please configure:

network-clock-participate wic 3

network-clock-select 1 E1 0/3/0

That will eliminate all errors on controller E1 and voice quality should improve.

Hope this helps, please rate post if it does!
