Hi all,<br><br>Try all echo cancelers available and choice the best one. If you have a digium board, try to install HPEC. There are a OSLEC that is good too (for some cases).<br><br>Regards<br><br><div class="gmail_quote">

Thank you Alexandre, worked like a charm!<br>
<br>
Also I added the line: "echocanceller=mg2,1-15,17-31" to system.conf<br>
and the echo is lighter now, but still there...<br>
<br>
I'll study a little about this tag, echocanceller, to see if I can<br>
improve my system...<br>
<br>
<br>
