I still need to experiment with it, so I am not sure yet. When I have it I will post the settings. I really don't have a clear understanding yet of the principles for using gain. Are there, for example, specific reasons for different settings. All I want is to be sure I can hear the other party, and they can hear me in the proper volume.

What gain settings work best for you? Gary Hello Bryce, Gain settings do seem to have an effect.

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.
