<div dir="ltr">The other interesting issue in this case is that the 192.xx.xxx.xxx address is not an RFC1918 address, but it is also not reachable from kamailio. Â That is why I hoped kamailio would trigger NAT traversal logic solely on the fact that the source and contact address are different.</div>

Actually the source IP seem to be identical to the topmost Via
address.<br>
<br>
But it should detect the private IP address in the contact header.<br>
<br>
Maybe you have an exception, that NAT traversal is not triggered, if
there is more than 1 Via header.<span class="HOEnZb"><font color="#888888"><br>
