If you pbx does not register by itself yes, a permanent contact should be added<br>
as fake register.<br>

ngcp system is capable of doing DNS SRV queries. If you add a permanent contact<br>
like:<br>
<br>
<a href="mailto:sip%3Auser@pbxdomain.com">sip:user@pbxdomain.com</a><br>
<br>
and <a href="http://pbxdomain.com" target="_blank">pbxdomain.com</a> has SRV records pointing to the three PBX systems with wight<br>
and priority, the ngcp system will read those values and use them.<br>
