Hi Lazlo,<br>
<br>
I do not understand - the LB + b2b refer capture shows a call going
through the B2B and receiving a 503.....there is no REFER stuff
there at all...<br>
<br>
Is there something I mis ?<br>
<br>
Regards,<br>

<br>
Could you post somewhere the SIP capture of the call ?
Just to be sure I correctly understand your scenario.<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" target="_blank">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>
