Hi Morten and everyone else.

The problem with Kamailio in front of FreeSWITCH still exists. After a lot of debugging etc. I think the problem occurs due to the IP FreeSWITCH receives from Kamailio.

My users are registrered with the IP from Kamailio in FreeSWITCH and not the IP address they comes from (which Kamailio sees).

So is it possible to setu Kamailio so FreeSWITCH thinks it receives the SIP packets directly from the SIP clients and not Kamailio?

Or should this not be the problem?

Because I think that's why FreeSWITCH send packets back to Kamailio instead of the SIP clients.

I guess FreeSWITCH shouldn't send packets back to Kamailio as Kamailio just is a dispatcher.

Hi Morten.

I've got the output from tshark when "Too many hops" occurs. And it's no wonder, as my FreeSwitch are sending the SIP packets to Kamailio and Kamailio are sending them back to Freeswitch.

What to do?

That is the complete capture. Without registration though. I'll send
another capture later with registrations.

Also, this failed with "Time out".
I'll try to create an event with "Too many loops" as well.
