A Class of Service (CoS) defines the privileges and the features assigned to a group of users. You can use the Class of Service page to define each CoS, create new CoSs, and change or rename existing CoSs. You can use the User Management page to assign a previously defined CoS to a user. The Basic and Mainstream licenses control the features. The CoS definitions determine which features are available for users assigned that CoS. The CoS definition determines whether a basic or mainstream license is required for users that use that CoS. The maximum storage size for a CoS is 65536 KB.
Messaging offers the following default CoSs that you can assign to each user:
Standard or Enhanced: To allow local and domestic long distance dialing.
Executive: To allow local, domestic long distance, and international dialing.
Info Mailbox: To create a message for an info mailbox. A typical informational message might include details about directions, business hours, weather, or human resources. You can record messages for an info mailbox that take up to five minutes to play. You cannot create an info mailbox by assigning the Info Mailbox CoS to the user.
Administrator: To send system broadcast messages. A typical system broadcast message contains announcements or instructions from the system administrator about the voice mail system. This CoS also determines which users can send broadcast messages. This CoS is unrelated to the administrative privileges handled through the Server (Maintenance) RBAC administration.
ELA: To use the Enhanced-List Application (ELA) mailbox capabilities.
