i had a similar problem a while ago. I solved it by defining
externip=xxx.xxx.xxx.xxx in sip.conf. It tells the remote SIP
client where you are.

Hi,
I've got a strange issue, that I haven't found addressed on the wiki.
My asterisk box is behind a firewall which routes udp/tcp requests on 5060 and
8000 to asterisk.
When I make a call from a Zap or SIP extension on the inside of the firewall
to any Zap or SIP extension on the inside of the firewall, everything works
find. I have access to voipjet, and when I place a call through them
everything also works fine.
However, I have several SIP extensions defined for remote users. They can
authenticate to asterisk and they can call me and I can call them. However,
whether I place the call or receive the call I cannot hear the remote user!!
They can hear me, though. (I'm inside the firewall).
My remote users are on XLite, if that makes a difference.
Anybody got an idea why the firewall is blocking traffic for these SIP phones,
but not for voipjet?
Thanks
lane
