<p>Daniel, received is FreeSwitch.<br>
As wrote above Kamailio do not send any data. Kamailio just send two packets.</p>
<ol>
<li><code>SYN</code> and receive <code>SYN/ACK</code> packet;</li>
<li><code>RST</code> packet.</li>
</ol>
<p>Also I start kamailio without <code>-x tlsf</code> arg with same config to same FreeSwitch, then Kamailio able send MSP message to FreeSwitch.</p>
