UA1(192.168.0.1) --> kamailio (internal:192.168.0.2 public:1.1.1.1) -->
UA2(2.2.2.2)
if in UA1 INVITE, I write KSR.rr.record_route().
so UA2(2.2.2.2) received sip msg (Record-Route: <sip:1.1.1.1:7080>), so Kamailio
can received BYE/ACK from UA2.
but,Kamailio can't received BYE/ACK from UA1.
if in UA1 INVITE, i write KSR.rr.record_route_advertised_address("192.168.0.2"),
then Kamailio can received BYE/ACK from UA1, but not from UA2.
what can i do, let Kamailio receive BYE/ACK from both sides ?
