[cisco-voip] 7900 Factory Reset w/out connecting to the network

[Charles Goldsmith]

No DHCP is needed, don't even need a live network to reset, just need power

you only need option 150 if you want it to try and update firmware, and of
course, it needs a phone config on CUCM to do that

for what a 7970 is worth as trade in or resell, it's too much work, a
hammer works better/faster :)
