<div>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. </div>

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