Hi
I've missed some of the email replies in this thread (I see them on
lists.kamailio.org website.)
- It's been suggested that NAT may be the root of the problem. However,
that can't explain how the 200-OK for the CANCEL and then 100-Trying for
the INVITE worked.
- Path and Record-Route headers were mentioned, but they're not relevant
for receipt of INVITE responses (and not relevant for this anyway because
you've TOPOS configured).
The size of the message (200-OK for the INVITE) is often significant. I
note that the INVITE was well over 1500 bytes, so I expect that the
response may well have been large too.
In my experience, when this sort of problem happens, there's often a
problem with IP fragmentation (a router not routing the fragments) or with
a misconfigured MTU on the network somewhere, quite possibly at the
asterisk machine. This is almost certainly an IP problem, not a SIP problem.

Samuel,
Have you used Path header?

Good evening everyone,
I’m trying to set a scenario with my extensions registered against
kamailio via wss and then once authenticated forward the register to my
asterisk.
After this, I use dispatcher module to balance invites to my asterisks.
I have a few questions, the first part seems to be working as I want but
when asterisk receives an invite and responds with INVITE (SDP) it doesn’t
appear on my kamailio (but every other message appears) You can see it in
this sngrep captures
Kamailio:
Asterisk
I guess it is because something in my asterisk pjsip configuration is
wrong but I can’t figure out what. So I’m start to think that maybe It is
because I need to configure an rtpproxy app to change SDP and make RTP
traffic go through kamailio
Maybe there’s something else I need to do, or there’s a guide to do this.
But I can’t find anything
Any help will be very appreciated
Thank you in advance
