[Asterisk-Users] Capi echo problems solved

[ismaelg]

Hello all,

A couple of days ago, I just asked the way to solve the echo problems in 
  capi channels.

After read a lot of web pages and news group, I just started to midify 
the file, /etc/asterisk/capi.conf.

All my capi channnels was configured in the same way.

msn=XXXXXXXXXX
incomingmsn=*
controller=1
softdtmf=1
accountcode=
context=outgoing
;echosquelch=1
echocancel=yes
;echotail=64
;callgroup=1
;deflect=12345678
devices=4

As you can see, only the "echocancel" parameter is uncoment.

This was not enough, because we continiuos earing our own echo in the 
capi calls.

Among to uncoment the "echocancel", parameter, I needed to change the 
Txgain and Rxgain values in the capi.conf file, to avoid the echo and 
get a good sound quality.

The values that worked for me are:

rxgain=0.4
txgain=0.6
