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.
