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.<br><br>--<br>Michael Boers<br><br><div><span class="gmail_quote">
