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

[Fuermann, Jason]

Sounds like the CM is not reachable from that phone, or possibly you re-entered it as the wrong model (although it should show registration rejected if you did that). We move phones between subnets all the time without a problem, with and without deleting them from the CM. I'd get the phones ip and check the diagnostic page on it to see what it thinks is happening.

Does it show the phone as registered?  The CCMAdmin IP address will be the last IP address CUCM saw that phone registered with.   You'll need to look at a packet capture and ccm traces to see why the phone isn't registering.

Are there other phones registered from that subnet?

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.
