Hi, yes Kamailio is listening to all addresses, even the destination
address and still no response. It is weird because it only happens with
172.. addresses. What I did for now is I put a MikroTik router between the
Kamailio server and the switch, and I configured it to do src-nat and
change the source address from 172.. address to 192.. address and now the
Kamailio respond!
So I fixed it but I don't like this solution.
I would like to find out what causes the problem so I can really fix it.
