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

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
