Beginner question ahead... be gentle. ;-)<br><br>I compiled FreeSwitch (except module mod_event_socket, see question #1), <br>tried to connect to my SIP service provided by my ISP (xs4all).<br><br>What I put in in freeswitch.xml
:<br><br>&nbsp;&nbsp;&nbsp; &lt;configuration name=&quot;sofia.conf&quot; description=&quot;sofia Endpoint&quot;&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;profiles&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;profile name=&quot;XS4ALL&quot;&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;registrations&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;registration name=&quot;xs4all&quot;&gt;
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;param name=&quot;register-scheme&quot; value=&quot;Digest&quot;/&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;param name=&quot;register-realm&quot; value=&quot;&quot;/&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;param name=&quot;register-username&quot; value=&quot;08787.....&quot;/&gt;
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;param name=&quot;register-password&quot; value=&quot;.....&quot;/&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;param name=&quot;register-from&quot; value=&quot;sip:100@what_to_put_here?&quot;/&gt;&nbsp;&nbsp; [***note***: what should I put here?]
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;param name=&quot;register-to&quot; value=&quot;<a href="mailto:sip:08787......@sip.xs4all.nl">sip:08787......@sip.xs4all.nl</a>&quot;/&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;param name=&quot;register-proxy&quot; value=&quot;sip:
<a href="http://sip.xs4all.nl:5060">sip.xs4all.nl:5060</a>&quot;/&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;param name=&quot;register-frequency&quot; value=&quot;20&quot;/&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/registration&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/registrations&gt;
<br>&nbsp;&nbsp; ....<br><br>So: what should I use for register-from?<br><br>It does not seem to work this way, in the log file I see &quot;received garbage&quot;<br>The log file shows:<br><br><a href="mailto:freeswitch@macserver.local">
