Hello,
Thank you for your reply. Indeed, I think that R-URI contains the kamailio
address.
Here is the full trace :

Hello,
you have to give all the BYE -- the best is to send from the first INVITE to
the last BYE, because it matters how the record-route are built for INVITE.
I suspect that the BYE comes with r-uri having kamailio address, if the old
ser does fix natted contact (which should not do in this case).
Cheers,
Daniel

Hello,
I work on interconnecting an old SER version with Kamailio.
When a BYE is sent by the old SER, the “if (loose_route)” instruction
returns false and then a “404 Not here” is sent. So the BYE is not relay to
the UA.
If the BYE is sent by Kamailio, no problem.
Here are the BYE headers received by Kamailio:

44e6af1efd45b74305a9a
Route: sip:KAMAILIO_IP_ADDRESS;lr=on
I looked at the RR module documentation and it’s clearly said that “The
loose_route function analyzes the Route: headers in the requests. [
]If a
Route: header is found, the function returns 1 and behaves as described in
section 16.12 of RFC 3261.”.
Someone has an idea?
Regards,
Igor.
