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 ？
