[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

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.

[asterisk-users] Increasing voice volume without getting echo or entered digit problem
Dear; I am talking about something else. When I said increasing the volume from the hardware, I was mean something else. Before when we were using Zaptel, we were able to do this (increasing the volume from the hardware) in the /etc/modprobe.conf but currently we are using dahdi and I do not know from where we can do it. Before, we can do it from modprobe.conf using below command: options wctdm fxorxgain=20.0 fxotxgain=20.0 So how to do this in the dahdi? There is a file /etc/modprobe.d/dahdi.conf, is it the right file? Or there is another file? Please advise.

/etc/asterisk/chan_dahdi.conf is where you control txgain and rxgain in DAHDI. -----Original Message----- From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of bilal ghayyad Sent: Thursday, May 10, 2012 1:37 PM To: asterisk-users at lists.digium.com Subject: Re: [asterisk-users] Increasing voice volume without getting echo or entered digit problem Dear; I am talking about something else.

Any *.conf file in /etc/modprobe.d will suffice but dahdi.conf is the convention. You can also accomplish this from the Asterisk CLI with "dahdi set hwgain". Type "dahdi set hwgain" on the Asterisk CLI for more information.

[asterisk-users] Increasing voice volume without getting echo or entered digit problem
I am sure there should be another place .. if I increased it from chan_dahdi.conf, the voice quality is bad and the calls will disconnecting while we are talking .. Increasing voice volume from chan_dahdi means increasing it at software level, I am sure there is a place to increase it at hardware level. Let us agree on something: Is settings to increase it at hardware level? In Zapata, it was existed and can be done as mentioned in my previous emails (from modprobe.conf), can we agree on this? If yes, so why it is not possible in dahdi?

Hello Bilal, You could try /etc/modprobe.conf Options wctdm24xxp Or Options wctdm Hope this can solve your problem Best regards, Anam.
