Do you have provisioning setup on your call manager?  If you do this may be preventing changes to the phone.

If you need a static IP you can put a reservation in your DHCP so the phone always gets the same IP, you can also set other DHCP options with a reservation.

You do not want to remove provisioning because then you would need to manually configure every single phone.

What is the ultimate goal with this phone?

But why do you need to assign IP manually?

If all you need is an IP that does not change your better option is to set a DHCP reservation, in general beyond servers/ network equipment you should not have any devices with static IP on your network.

Where is it getting it's IP from?  Is this a new phone or did you buy used?

If you purchased used I would advise a full factory reset of the phone.

have you tried factory reset of the phone, it seems like it still has the configuration from the old site.
