Hi Bilal,
High volume is always a big for echo cancellation. 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.
Regards,
Valer

Subject: [asterisk-users] Increasing voice volume without getting echo or
entered digit problem
Dears;
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)?
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
Using txgain and rxgain from chan_dahdi.conf will not help, it will increase
the voice volume but with the following problems:
1) Suddenly the call will be disconnected while we are talking.
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).
3) Echo problem.
So I need to know how to increase the voice volume from another place?
Appreciate the kindly help.
Regards
Bilal
