Do not post in older dead threads.

Start a new one, include a complete description, and configuration.

This is a issue with UCM and CME:

The issue turns out to be that the phone firmware needs to be at 8.5.2 before having the ability to upgrade to the latest.
Please do not use: 8.5.2sr1

Firmware Upgrade Issues for SCCP
Note For all SCCP firmware upgrades from firmware release versions earlier
than 8.3(3) to version 8.5(2)SR1 or greater, you must first upgrade your
firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you
can upgrade your IP Phone to version 8.5(2)SR1 or later.

If this helped please rate.

Any questions please let me know?

Kind Regards,
