Hello. Thanks for your reply .
I understand about nat . Am i right that even without nat traversal
logic i have to see on proxy itself attempts to connect to private ip
addresses ?
But i not see them.
Ok i changed "== false", to "!= true". I prefer to use long condition
forms to have better config file readability.
But i am not sure that even my "==false" which in block
onreply_route[REPLYROUTE] can influence on something because xlog
operator stay before condition and i have to see a least message that
packet reached onreply_route .
To make capture i using "ngrep -d any -qt -W byline port 7060" it listen
on all interfaces and result exactly same as bug report on github.
I attached debug log from kamailio on system where issue persist. Well i
replaced some private information inside it to avoid voip frauders to
collect information. But privately i can send original ones if needed.
Affected host does not have firewall configured.
It have two ip addresses(two physical interfaces) . One of them assigned
public address, another private (10.34.79.254/20). REGISTRAR in same LAN
segment with proxy private ip address.

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
