Hi there,<br><br>I got another question. <br>We use several digium cards without hardware echo cancelation.<br>The software echo cancelation does not work well at the moment - especially at<br>the beginning of the call. I already read the articels about echo on voip-info.
<br>Is there a rule of thumb or best practice how to find the correct settings or<br>is it just try and error?<br><br>Thanks<br>Chris<br>
