Hello Bryce, Gain settings do seem to have an effect. I am going from a Cisco 7960>Asterisk>Zap TDM Card>POTS

I don't know what kind of phones you're using, but for Asterisk to even be able to detect DTMF tones on our Sayson / Aastra 390s and 480s, our FXS channels are set to -5.0 on both rx and txgain. If you're using externally-powered phones (as in not your ordinary joe-schmoe analog phone), I have found that they're usually pretty "hot" (loud) and Asterisk can't understand what is said. Good luck! Regards, Bryce Chidester Rhino Equipment Corp.
