st1\:*{behavior:url(#default#ieooui) } Do you have reinvites
enabled? Are you running this over a linksys four port SoHo router/switch or
something?
Thanks,

Subject: Re: [asterisk-users] Bad Echo between SIP calls
Steve I understand your theory. We have Poycom 501 phones. Prior
upgrading to PRI we were till date using 4 analog lines connected with TDM card
from digium & no echo for pure SIP to SIP lines.
Now I have TE212P which had onboard echo cancellor.
I am trying make myself clear before I blame on any network. B'cos for
sure we have a spegati of networks & no QoS. Also the intresting thing is if I
call from one extension to other dialing the main line & then extension the
call is crystal clear. but when dialing a direct extension its a hell of echo.

If you are getting echo on pure SIP to SIP calls, there's no point in
fiddling around with your zapta.conf. That file is for configuring
chan_zap, which is used to talk to Zap/ channels. Your calls are SIP
to SIP so the zap channel and your PRI aren't being used at all.
SIP calls are "pure digital" 4 wire lines so no electrical (Hybrid)
echo will be present. The phones should not generate echo. If they
are, they are presumably nasty phones (what kind are they?) and you
should get properly made phones.
