Hi 

i have some kind of issue with BYE
Asterisk send invite to Kamailio1, Kamailio1 proxy to Kamailio2, Kamailio2 found UAC and send invite to it.
UAC response 200OK -> Kamailio2 -> Kamailio1 -> Asterisk.
Session established.

But then UAC sending BYE to Kamailio2 , Kamailio2 sending it to Kamailio1 and Kamailio1 response 404 not here (not sending BYE to Asterisk)

Any suggestions?
