[cisco-voip] CUCM 7.1 - adding IP Phone device

[ATKSI]

I am moving an IP Phone from one subnet/user to a different user on a
different subnet.

I have deleted the IP Phone configuration in call manager; however, when
adding the same device (same MAC address) again in the call manager, the
call manager associates the phone with the old IPv4 address (even though the
phone is turned off).  The phone is booting up and getting a different IP
address on the new subnet, and is always in the "Registering" state.  The
phone has the right CM IP, TFTP IP, etc. the only difference is the phone IP
address and the IP address that the CM is showing in the phone device
configuration.  I also tried resetting/rebooting the IP phone.

In general where does the CM get the device IP address from?

Thanks,

George.
