Hello
Did you call the loose_route() function for the BYE? It should just
work; that's one of the basics of how kamailio works, so I'll be very
surprised if there's somehow a bug in kamailio.
If that does not work, perhaps send a list of the listen directives in
the kamailio.cfg, along with the headers of the two SIP BYE messages
(incoming and outgoing) and I'll see what I can figure out for you.

Hello all,
I’m using Kamailio as SIP proxy between session manager and SBC.
I came across an issue in BYE request where the SBC sent in the header list of Routes
where first route is Kamailio IP, and the second is SM IP, in addition to other routes
(last route is the caller party)
What Kamailio did is to route the BYE to the address set in the Request-URI, which is the
caller party.
What should be done instead is that Kamailio should remove the Route header including its
own IP, and route the BYE to the next hop which is in this case the SM IP.
How to accomplish that?
Following is the Route header in the BYE request coming from SBC:
[truncated]Route:
<sip:KAMAILIO_IP;lr;ftag=xxxxxxxxxxxxxxxxxxxxxxx>,<sip:SM1@SM_IP;transport=udp;lr;av-asset-uid=xxxxxxxxxx>,<sip:127.0.0.2:15060;transport=udp;ibmsid=local.xxxxxxxxxxxx_xxxxxxxxx_xxxxxxxxx;lr;ibmdrr>,sips:127.0.0.2:15061;ibmsid=local.xxxxxxxxxx_xxxxxxxxxx_xxxxxxxx;lr;ibmdrr,
sip:SM1@SM_IP;transport=tls;lr;av-asset-uid=xxxxxx,
sip:CALLER_PARTY_IP:5061;transport=tls;lr
