<p class="MsoNormal">That's a good explanation, I believe they use socket.h for socket(), bind(), connect(), recv(), send() etc.<o:p></o:p></p>

<p class="MsoNormal">" I think that proto 3 in OpenSIPS is TLS, but I don’t have a reference for that one." - I have doubts regarding this, since I don't have any TLS in my network.<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">To be honestly it's almost impossible that TLS would appear within it.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">But that's a good thought, I hope some of OpenSIPS project developers will clear our this for me.<o:p></o:p></p>
