<p>I just tried the current master (commit: <a class="commit-link" data-hovercard-type="commit" data-hovercard-url="https://github.com/kamailio/kamailio/commit/4efe19f64d8bb787d2d620a833f5dd29619fa588/hovercard" href="https://github.com/kamailio/kamailio/commit/4efe19f64d8bb787d2d620a833f5dd29619fa588"><tt>4efe19f</tt></a>).<br>
I see that the request is not sent out by Kamailio at all.<br>
tcpdump and syslog:  <a href="http://updates.xorcom.com/~xorcom/tcp-4efe19f64d8.tar.gz" rel="nofollow">http://updates.xorcom.com/~xorcom/tcp-4efe19f64d8.tar.gz</a><br>
Ref. OPTIONS request (packet 67 in the tcpdump-4efe19f64d8.cap, line 2869 in syslog-4efe19f64d8)<br>
The expected path: Asterisk (10.28.80.47) -> Kamailio(10.28.80.47)--Kamailio(192.168.9.103)->SIPPhone(192.168.0.178)<br>
In reality, the message is accepted by Kamailio at 10.28.80.47 and not set out.<br>
Like in v. 5.2, the messages are forwarded correctly if I remove the 'listen' parameters.</p>
<p>Kamailio configuration:</p>
<pre><code>tcp_connection_match=1
