[Asterisk-Users] DTMF not working

[Peter Osborne]

Hi all,

I just upgraded from Asterisk 1.0RC1 to Asterisk 1.0.7 and our dtmf no longer 
works with external phone systems. I have a Wildcard TDM400P with 4 FXO's? 
(it connects to analog lines). No changes were made to the config files.

Here's my config:

/etc/zaptel.conf
fxsks=1-4
loadzone = us
defaultzone=us

/etc/asterisk/zapata.conf
[channels]
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echotraining=yes
rxgain=2.0
txgain=2.0
callgroup=1
pickupgroup=1
musiconhold=default
context=incoming
group=1
signalling=fxs_ks
echocancel=64
echocancelwhenbridged=yes
relaxdtmf=yes
channel => 1-3
