Input Gain/Output Attenuation

Hello,
On the gateway T-1 PRI under Product Specific Configuration the settings for Input Gain (-6..14 db)* and Output Attenuation (-6..14 db)*

I have several users complaining of echo and that they have a hard time hearing the other party on the phone.

Currently I have the Input Gain set at 5 and Output Attenuation at 9.

If  I need to increase the ear piece volume so the user can hear the other party which one should be adjusted? And which way? Negative or positive.

Also to remove the echo (which isn’t constant or very much) does anyone have a set of settings that worked for them?

Increasing the input gain will make the audio louder for your users connected to the gateway.

To get rid of echo you can turn on echo cancelation. Its not normally needed for a digital circuit but if you are experiencing echo then turn it on. You may find that adjusting the gains helps the echo cancelation anyway.
