<tt>Hi Lazlo,<br>
<br>
Could you post somewhere the SIP capture of the call ? Just to be
sure I correctly understand your scenario.<br>
<br>
Regards,<br>

<div>Hello,<br>
<br>
<br>
</div>
Just tried to play with the b2b refer scenario with
opensips.<br>
</div>
The config is pretty much the default LB config from <a
moz-do-not-send="true" href="http://opensips.org">opensips.org</a>,
so nothing sexy in the conf, it works fine without the b2b
stuff. LB destinations are reachable through the private
ip of the server.<br>
<br>
</div>
if I use the b2b topology hiding scenario, it also work
fine.<br>
</div>
when I use the refer scenario, things goes mad :)<br>
<br>
</div>
Sending this to the caller party (default LB config):<br>
