Hello, is Kamailio listening on all the IP addresses you need to received the traffic? You can do: kamctl ps Also, check if you have any firewall rules blocking traffic from those IP addresses.

I recently connected with another company that is supposed to send me calls through the Kamailio server. The problem is this: I am connected to then with a cable from their network to mine. My port has the address 10.9.18.198 and they come from the address 172.18.177.18. When I get packets from their address (172...) I can see them getting to my Kamailio server, but the Kamailio does not respond. It only happens when I get packets from 172 source address. If I get from 192 or 10 adresses from my LAN network it works, and if I get packets from real world IP's through my WAN it works. Does anyone have any idea why the Kamailio does'nt respond to packets from 172 adresses? And how to fix this?
