<div dir="ltr"><div>Hi Paul,<br><br></div>Using ngrep/tcpdump shows the packet clearly going from the Kamailio server and arriving at the Asterisk server. This is why it's a mystery that Asterisk doesn't see the call coming in. We tried removing the firewall (so iptables -L shows no rules at all) but that didn't help unfortunately.<br>

</div>Well, you need to use tcpdump on each hop across your network. If are<br>
Asterisk is not getting anything, either it is not receiving anything<br>
(check transmit side) or the firewall is dropping it.<br>
