<p>Hello,</p>
<p>not sure I understood properly your issue, but if it is that the
BYE is not getting to your dispatching/distribution rules, then
all should be fine, because BYE (and other requests withing
dialog) should be routed with 'record routing', therefore be sure
you do record_route() from initial INVITE of the call and
loose_route() for requests within dialog. In case you look at
default kamailio.cfg, it has this kind of logic in it.</p>
<p>Cheers,<br>
