<p>thank you. Was a little bit tricky to install it as our slapd isnt in the right version.. But it seems to work now.. Error messages no longer appear.<br>
</p>
<p>Now the message is quiet better: </p>
<p><br>
</p>
<p>9(9381) INFO: rtpengine [rtpengine.c:1627]: rtpp_test(): rtp proxy <udp:127.0.0.1:22222> found, support for it enabled<br>

<p>Again, thank you!<br>

<p class="MsoNormal">As we wan to start a call session, the P-CSCF answers with „403 - Forbidden. You must register with an S-CSCF“…</p>
