[Asterisk-Users] Running down an echo problem on outgoing calls

[Jim Freeze]

Hi

I am having some echo on outgoing calls on a pstn line (made from a  
sip phone)
and am looking into some fixes involving rxgain and txgain, but
before I go down that road, I want to make sure I have everything
setup correctly.

My zapata.conf has
  cat /etc/asterisk/zapata.conf
[trunkgroups]
; define trunk groups

[channels]
; hardware channels

; default
usecallerid=yes
hidecallerid=no
callwaiting=no
threewaycalling=yes
transfer=yes
echocancel=yes
echocancelwhenbridged=yes
echotraining=yes
signalling=fxs_ks

; define channels
context=pstn-incoming
channel => 1-4


But, when I run asterisk and ask it about the zap channels, I get  
that echo cancellation
is OFF.

zap show channel 2
Echo Cancellation: 128 taps, currently OFF

Can someone please explain this?

Thanks

Jim Freeze
