Any way to individually configure physical Zap ports

Asterisk Asterisk Support

Hi there,

I have a situation where I will have 4 regular Telco lines coming in and 2 Vonage lines via ATA. I would like to be able to adjust the gains and echo cancelling settings individually. Either by TDM400P card or preferrably each individual FXO module.

Is there any way to do this in Asterisk?

Hi mustardman

Im not for sure but I believe zap channels can be configured indpendantly
in the zapata file

Yes, you can do it in /etc/asterisk/zapata.conf:

Defalut values are :

rxgain=0.0
txgain=0.0

… and you can adjust this settings per-port basis
