DNS, IP tables, NTP and DHCP are among the few services that some folks configure separately on sipxecs 4.4 or older systems. Starting with the 4.6 release these services are integrated in a much tighter way. In order not to conflict with any custom configuration methods, these select services now have a "Unmanaged" setting you can set which allows you to configure the services yourselves.
