Thanks for the suggestion. I am using a tdm400p with 4 fxo channels. I am
in the US, so opermode should not be ok at default settings. I just
recently got fxotune working on my system. The version that comes with
zaptel 1.2.16 would simply hang. I am using the 1.4 fxotune now with the
1.2.16 driver. That has reduced the echo coefficient from 35% to 8%. We
will see how that does.
