I performed the afrorementioned test: removed network connection from the mbu. INternal and all dhcp servers disabled. Phone did not connect to the system. However, upon switching it to static and [NOT] yet setting an IP address the system assigned it a 10.0.0.10 address. So where did it get that from. This test was just the phone and phone system. Nothing connected and dhcp i thought disabled. By that i mean in the programmer all of the DHCP fields have a zero in them. Is there actually a disable enable switch i should be looking for?
