<span class="Apple-style-span" style>My whole configuration is:</span><div style>[Sip clients] < = > Kamailio 3.2 <=> Asterisk servers (behind Kamailio)</div><div style>Asterisk servers have only local IP addresses, and I use t_relay instead of forward.</div>
<div style>Kamailio runs on same server as rtpproxy.</div><div>Everything is fine if clients connect to Kamailio with its IP address - global, or if they are behind Kamailio with local address.</div><div>When clients connect to Kamailio using <a href="http://sip.ourcompany.com">sip.ourcompany.com</a>, then call (video also) is OK, but ACK and BYE do not work.</div>
<div>BYE receives not here (404), and ACK die somewhere.</div><div>I forward BYE and ACK in case when src_ip==$td to Asterisk server.</div><div><br></div><div>If one of clients use IP - then calls initiated from it are OK (BYE/ACK - are going correctly - to Asterisk and to other client also).
