<div dir="ltr"><div><div><div><div><div><div>Thank you so much for pointing me in the right direction! It was the missing alias. Now the extensions are working, but there's one more problem: When I call the PBX (echo-test) or from one extension to another, I get a hangup because Asterisk doesn't seem to receive an ACK from the client:<br>
<br>"Retransmission timeout reached on transmission OGNkYTY1ZmJmY2VmMjQ2YmM4MWU1YWY0YjU3NjlhYjA for seqno 2 (Critical Response)"<br><br></div>I have attached the log for two local calls that hangup after about 30s and the sequence for an incoming call from one of the trunks that works without problems. So you can map all the IPs:<br>
<br>--------<br></div>198.23.139.21 (5060): Kamailio<br></div>198.23.139.21 (5080): Asterisk<br></div>--------<br><a href="http://192.168.178.33">192.168.178.33</a>: Home network local IP<br></div><a href="http://188.105.112.187">188.105.112.187</a>: Home network external IP<br>

Do you (or anybody else) have any idea where to look in order to solve this problem?<br>

<div dir="ltr">Sure, here's the sequence for an inbound call via the "LPhone" trunk that was supposed to go through to extension 1001. The extension was set to "NAT" in the FreePBX settings. Just ask if you need more background.<br>

<div><br></div><div>for some reason Kamailio is not recognising the user. Could it be that you do not have the ip 198.23.139.21 set up on Kamailio as an alias, or that the user 1001 is registering to a different domain?</div>

<div dir="ltr"><div><div>Thank you very much for sharing your insights, Barry! I am facing the same problem that Trevor described: <br><br>Things are working just fine on their own, but as soon as FreePBX comes into play, calling extensions becomes impossible because of the different tables used. Removing the password from FreePBX (and setting the Kamailio IP in the ACL field) seems to mitigate the issue somewhat, but even though the extension shows as registered in FreePBX, it always shows as busy:<br>
