A system administrator needs to grant additional privileges to a single Cisco Unified Communications Manager user. How should the administrator accomplish this task?

In CUCM, Roles cannot be directly assigned to individual users; Roles are assigned to Access Control Groups, not to users themselves.

Users are not added to Roles directly; Roles are permission containers that are bundled into Access Control Groups, which users are then members of.

Access Control Groups are not assigned to Roles - the relationship is reversed: Roles are assigned to Access Control Groups.

CUCM uses a role-based access control model where Roles define specific resource access permissions and Access Control Groups are collections of those Roles. To grant a user additional privileges, the administrator adds the user to an Access Control Group that contains the desired Roles. This is the correct and supported method for privilege management in CUCM end-user administration.
