context=incoming
signalling=fxs_ks

usecallerid=yes
cidsignalling=v23
cidstart=ring
callerid=asreceived

busydetect=yes
busycount=6

echocancel=yes
echocancelwhenbridged=yes
echotraining=yes
echotraining=800

rxgain=9.0
txgain=4.0

channel => 1

i tried various rxgain/txgain settings, also commenting out echotraining, but 
havn't noticed any difference

zaptel.conf:

fxsks=1

loadzone=pl
defaultzone=pl
