Dear experts,
I am using Openvox TDM400P cards, everything so far is working as expected BUT the only issue I have is with the volume (rx and tx)..

How do I increase the volume of my FXO lines?

I want to confirm if what I did is correct..
I edited the: rxgain=4 & txgain=4 inside zapata.conf file as mentioned at Elastix without tears but not specified clearly what it does..

Is it the correct way of doing it (which is to change from 0 to any number above which I don't know the limit..)?

The same question applies for my SPA3102 which I am using it as well as a PSTN interface in addition to the OpenVOX card.. but with my SPA3102 I have no clue which should be done in order to increase the very low volume..

Yes it's rx and txgain.
The value is: dB.
By default all volume can are 0dB.
If you put a 4 to rx or tx gain, the gain is to +4dB
If you put a -1 to rx or tx gain, the gain is to -1dB.

Modify these values and try it.
