<div>Hi, <br> Yes, I have changed it. I tried as you have done, I put txgain and rxgain to "0" and it was possible receive and send faxes. I'm using two TDM400P (FXS with 4 ports and FXO with 4 ports). In my tests I'm sending faxes to asterisk from fax machine connected to one of the FXS ports.
</div>
<div>The problem is, if put tx and rx gain to 0 in the conversations coming from FXO channels hear very very low.</div>
<div>What can I do then, any idea ?</div>
