Outbound Zap calls not detecting answer

Have an issue dialing out from * on a TDM400P. The call is delivered to the PSTN, the far side rings, is picked up, but * does not detect the answer. Inbound calls work fine. Suggestions will be greatly appreciated!

zapata.conf:

[channels]
language=en
#include zapata_additional.conf
context=from-pstn
signalling=fxs_ks
faxdetect=incoming
usecallerid=yes
callerid=asreceived
echocancel=yes
callprogress=yes
busydetect=yes
busycount=5
progzone=us
echocancelwhenbridged=no
echotraining=800
group=0
channel=1-4
hanguponpolarityswitch=yes

zaptel.conf:

fxsks=1-4
loadzone = us
defaultzone=us

Hi

try changing callprogress to no,as analog callprogress is very hit and miss

Ian -

I’ll name my next wife after you :smile:

Sometimes the most obvious are the most overlooked.

Thanks!
