Are you trying to register the phone to CUCM? CME? If one of these, make sure the phone has a TFTP server configured either manually or via DHCP option 150. The firmware will update to the version configured on the server. If you do not have either you can update the firmware via a 3rd party server. Take a look at the following link.
