Hi Merrilee,
Here are the pre-defined CUC Roles that can be assigned;
Roles
Cisco Unity Connection offers levels of privileges for administrator accounts, set according to a list of predefined roles. Roles specify which tasks administrators can do. Before you add administrator accounts, select the roles that are assigned to each account. You can change which roles are assigned to the accounts at any time.
Connection comes with the following predefined roles. To see the specific privileges for each administrator role, in Cisco Unity Connection Administration, expand System Settings > Roles and click the name of each role. You cannot make changes to the permissions that are associated with each predefined role.
Audio Text Administrator | This role allows an administrator to manage call handlers, directory handlers, and interview handlers. |
Greeting Administrator | This role allows an administrator to access the Cisco Unity Greetings Administrator, a Connection phone conversation that allows users to manage the recorded greetings for call handlers by phone. Note  You need to assign this role to a User with Voice Mailbox account because the administrator must be able to access Connection by phone. |
Help Desk Administrator | This role allows an administrator to reset user passwords and unlock user accounts, and view user setting pages. |
Remote Administrator | This role allows an administrator to administer the database by using remote tools. |
System Administrator | This is the top-level Connection administration role. This role allows access to all Connection administrative functions, including all user and system settings, all reports, and all administration and diagnostic tools. The default administrator account that the installer specified during initial setup of Connection is set to this role. A System Administrator is the only role that has permission to create administrative accounts. |
Technician | This role allows an administrator access to all functions that enable management of the Connection server and phone system integration settings; administrators with this role can also run all reports, use diagnostic tools, and view all system and user settings pages. |
User Administrator | This role allows an administrator to manage user accounts, access all user administration functions, run user-related reports, and use user administration tools. |
While you can assign roles to users with voice mailboxes, we do not recommend it except when allowing access to the Cisco Unity Greetings Administrator. As a best practice, make sure that administrators have two accounts: one without a voice mailbox for administering Connection and another with a voice mailbox that they can use to access their personal mailbox.
