CUCM 10.5.1 - getting error when adding or updating a phone

[Yort Mantup]

We just upgraded from 8.5 to 10.5.1 last weekend.  Have an issue when trying to add or make changes to a phone that the following error occurs:

"Add failed.  The Insert privilege is required for this operation"   I do not get this error but the client service desk does.  I mimic my permissions with one of the client services desk and had them try again and still no change.  When they make a change, the change does save.  However adding phones is not allowed resulted in the same error.

Anyone else run into this?

open CUCM Pub CLI and enter command "utils system enable Administration" to unlock the config change and enable GUI administration for configuration and service.

This is the correct answer, albeit 4 years late.
