<p>Hi Razvan,</p>
<p><br>
</p>
<p><span>I know this is like a fantastic story, these points have already been proven;
<br>
</span><br>
1.- source and destination over 5060 port for all SIP traffic<br>
2.- I don't use Pike<br>
3.- No firewall rules<br>
4.- Selinux is disabled</p>
<br>
I am not tracing with Debug but I set xlog just below route{ and onreply_route{<br>
<span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">T</span><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">he
truth is that I am baffled... </span><br>
<br>
<span>Could it be that Opensips does not detect these messages as SIP type? Or something like that?<br>
</span><br>
Thank you very much.<br>
Regards.<br>

<div><tt>Hi, Jorge!<br>
<br>
If you are saying the 200 OK is not even logged (are you tracing with Debug), it means OpenSIPS doesn't see it. I would check:<br>
1. the 200 OK is sent to the proper port<br>
2. Pike is not blocking the reply<br>
3. local firewall does not block the 200 OK<br>
4. selinux is disabled<br>
<br>
Best regards,<br>
</tt>

<div>Hi all,</div>
<div><br>
</div>
<div>I've been using OpenSIPS for a long time and I have never seen anything like it.</div>
<div><br>
</div>
<div>The schema is very simple, OpenSIPS exchanges SIP traffic between SBC and Asterisk PBX, during a fax call in response a REINVITE packet a 200 Ok is ignore by OpenSIPS, not even writes in log, as if this packet did not exist. OpenSIPS always ignores the
same SIP packet and its retries.</div>
<div><br>
</div>
<div>The sniffer on the Opensips interfaces shows that the packets are arriving correctly.</div>
