This is a great idea. We could define a dedicated group for
un-provisioned (discovered) phones. That group could include the calling
permissions and other things we can configure at the group level. Would
we need such a group added as a new default group in the system?

We cannot make any assumptions around where the DHCP server runs. This
has to work independent of whether sipXecs provides DHCP or any other
host somewhere on the network. 

One key objective is to get this to work across a routed network.
Retrieving and analyzing DHCP logs from different DHCP servers will not
work.
