The problem is that the signal reaches saturation and therefore reduce the effectiveness of the detection/convergence. If your existing echo cancellation can not handle it, you might want to try a different algorithm for echo cancellation. Try the PBXMate to see it resolves the problem in your case.<br></span></div><div><br></div><div>Regards,</div><div>Valer</div><div><br></div> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div dir="ltr"> <font face="Arial" size="2"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> bilal ghayyad <bilmar_gh@yahoo.com><br>

Dears;<br><br>How I can increase the voice volume in the analogue line (at dahdi port) without getting a problems in the entered digits (when using Background function)?<br><br>I got to know previously that it is possible to increase the gain at hardware and not software, this is better to avoid getting a problems. But where? I am using DAHDI 2.4 and another machine has DAHDI 2.6<br><br>Using txgain and rxgain from chan_dahdi.conf will not help, it will increase the voice volume but with the following problems:<br><br>1) Suddenly the call will be disconnected while we are talking.<br>2) When calling the Asterisk box and we entered the digits, it is failing to collect it (sometime does not collect it correctly and sometime it collects the digit duplicated).<br>3) Echo problem.<br><br>So I need to know how to increase the voice volume from another place?<br><br>Appreciate the kindly
