Hello,
the contact in 200ok (as well as INVITE) have GRUU addresses, not the
end point IP:PORT. For INVITE, you do set_/add_contact_alias(), but it
is not done for 200ok.
If you enabled GRUU for registrar module, it should work without
set_contact_alias(), by doing lookup("location") for requests within
dialog. If the GRUU is done by devices without being enabled in
Kamailio, try with set_contact_alias() for 200ok.
Then, do not forget to use handle_ruri_alias() for requests within dialog.
Cheers,
Daniel

Hello,
you have to provide the PCAP (or ngrep output) for such a call taken
on kamailio system to see the headers of each sip message and try to
understand where the issue is.
Cheers,
Daniel

Hi,
Do you need further information? Actually, I am not sure if the
process is normal, there‘s no problem with the call at least.
Could it be caused any problem if all clients do fix_nated_register?
Best Regards,
Rex

Hi Alex,
Thanks for your reply.
ICE/STUN haven’t been activated by our clients. All transmission
traffic pass through a proxy server. Below is the screenshot of a
normal call process.
Best Regards,
Rex

It's a tell-tale sign of an end-to-end ACK from the caller not
being forwarded properly to the callee. The server should not be
forwarding such an ACK "to itself"; this suggests that its Request
URI may be improperly constructed (it should be equivalent to the
remote Contact URI of the callee in the 200 OK message), or that
its Route headers are somehow incorrect (they should mirror the
Record-Route set in the 200 OK).

Hi,
It’s weird that the calls always drop after 32s
while the callee is
using public ip. Also, Server forwards ACK to itself with
UDP,
instead of forwarding to callee with TLS.
Moreover, I cannot see “Received”in AOR as the
callee finish the registration.
I recognized it’s marked by nat_uac_test(“19”)
and set with fix_nated_register(),
the problem can be resolved.
My scenario is as below, for your reference.
1.Kamailio version is 4.4.7, listening public ip.
2.Caller it’s behind NAT.
3.Clients of Linphone.
Do you know the reason why it happened?
Best Regards,
Rex
