Hello,
if the device is behind nat router, you have to do the nat traversal logic, because the Via header will be a private IP address, which cannot be used for routing by Kamailio.
To troubleshoot further, set debug=3 in kamailio.cfg and test again. Grab all log messages printed by kamailio in syslog (there should be a lot with DEBUG:...) and send them here. Also, get the pcap file with sip traffic for such case. It helps seeing what addresses are in the SIP headers.
Moreover, remove all those " == false ", as I said in the github issue, that can be something not giving what you would expect.
Cheers, Daniel

Hi, Thanks for your solution.
I tried to use it from early beginning and this is was a reason why i created bug report on github.
When i start tcpdump on proxy. I see 404 reply from REGISTRAR to Proxy. But not see reply from Proxy to UA.
Look like that Kamailio don`t think that 404 reply is a part of transaction.
