[cisco-voip] Firmware question

[Anthony Holloway]

I think the answer the question is: No, not in CUCM.  You will need to
utilize one of your backups.  Whether via a DRS restore in a sandbox
network, or with the DRS backup decrypter, or something else.

The other options mentioned, are basically looking for what versions your
phones are currently on, or what alternate COPs were installed, but not
necessarily do these things match what was in the Device Defaults page.  I
will admit, they are good options, just that they have a chance of being
wrong.

I think I know what happened to you: you did an install, and want to revert
the setting back, but don't know what it was set to before.

I highly recommend you use BAT > Import/Export to export the Device
Defaults before an upgrade, just like you would check device registrations.
