Hello,<br>
<br>
is kamailio listening on both externalip and internalip? Do you have
ip routes from externalip to FS ip?<br>
<br>
You can try with mhomed=1 or force the send socket with
force_send_socket() or assignment to $fs.<br>
<br>
Cheers,<br>
Daniel<br>

<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So an interesting one here. I’m doing pass
through registrations using the dispatcher module in Kamailio
and I’m using the Path Module to set the Path header In
Register request so that Freeswitch knows to follow the route
via Kamailio to find the sipPhone in future.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In summary:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">[SIP
Phone]------[NAT]------[(externalip)Kamailio(internalip)]-------[FS-Registrar]<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The problem I’m having is that the Path
header is being added with the external ip address of the
Kamailio instance not the internal ip e.g. “Path:
<a moz-do-not-send="true"
href="sip:%28externalip%29;transport=tcp">sip:(externalip);transport=tcp</a>”
which mean FS doesn’t root new calls out to the SIPPhone
correctly via kamailios internal ip.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have noticed that if I remove the
;transport=tcp from the FS-Register address in my dispatcher
group so that the last hop (from kamailio to FS-Register) is
done over UDP then the problem corrects itself. (although
this does present new issues whilst calling out back along the
path from FS, and we also have a prerequisite to use TCP so
this doesn’t help).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Has anyone had any experience of this
issue? I can’t see what I’ve done wrong here.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Many Thanks<o:p></o:p></p>
