[Asterisk-Users] Can't receive Faxes with Asterisk (help)

[Steve Totaro]

I dont know if it will work or not but have you tried setting each card up with different gains?  

I am not sure if the variables are global or not, but when I installed an FXO card on an *@Home box and used genzaptelconf, it created a separate file for the FXO with its own rx settings and was included in zaptel.conf.

      Hi, 
         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. 
      The problem is, if put tx and rx gain to 0 in the conversations coming from FXO channels hear very very low.
      What can I do then, any idea ?

        Have you changed the RXGain or TXGain?

           I can send faxes if I use RXGain= 20.0 but I can not receive unless I
        have the RX and TX set to 0.
