I'm running cvs-head from about a week ago with all stock parameters
including echo can. Zapata.conf looks like:
context=inbound-bus-dialin             
signalling=fxs_ks
group=1
echocancel=yes
echotraining=800
echocancelwhenbridged=yes
usecallerid=no
hidecallerid=no
callwaiting=no
callwaitingcallerid=no
threewaycalling=no
rxgain=5
txgain=0

I'm about 7db from the central office, so the gains have been tweeked
to work with those pstn losses.

It _seems_ like folks with snom phones and a TDM card have more issues
with echo then others. Could be wrong though. I'm using Cisco 7960's.
