[SR-Users] uac +kamailio + dispatcher + asterisk

[Daniel-Constantin Mierla]

Hello,

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.

Cheers,
Daniel
