We recently moved from a CME to a Call Manager. The way we are set up requires us to input static IP addresses on the phones. However when we made the switch a few of the phones went to the upgrading screen and displayed their MAC address. We tried resetting, power cycle, and even factory reset on one, but when they are powered on, they get to the point where they display the Cisco logo screen then go to the upgrade screen.
Some of the other phones that were on the old CME are working once we programmed the IP addresses.
Any suggestions on how to clear the upgrade screen so we can input the IP address?
That is the overall firmware version. It is obtained from CCO download area (restricted to customers with a support contract) in form of a zip file that contains 7 individual files. All must be accessible to the phone when it upgrades via TFTP.
CM has his own embedded TFTP server with which I'm not familiar to, but the principle is the same.
