Hi James,
Yes I'm using loose_route() and it's returning 1, but BYE message is not routed
anywhere.

Subject: Re: [SR-Users] SIP Proxy : BYE next hop
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.
