<div>Hi</div>
<div> </div>
<div>I had a similar issue, digium card with echo canceller. I was under the impression that the EC was turned on by default, while it actually requires explicit activation.</div>
<div> </div>
<div>in ss7.conf :</div>
<div><br>; Echo cancellation<br>; echocancel can be one of: no, 31speech (enable only when transmission medium is 3.1Khz speech), allways<br>echocancel => allways<br>; echocan_train specifies training period, between 10 to 100 msec<br>
echocan_train => 100<br>; echocan_taps specifies number of taps, 32, 64, 128 or 256<br>echocan_taps => 128<br></div>
<div> </div>
<div>-- note that allways is spelt with 2 l</div>
<div> </div>
<div>You may search some of my posts on this list archive - I had an issue w/ the EC resetting, and some digium staff helped me through this list.</div>
<div> </div>
<div>Hope this helps</div>
