/mcp• Application Administrator is a user without a mailbox that provides access to Cisco Unity Connection Administration, Cisco Unified Serviceability, and Cisco Unity Connection Serviceability web pages. • Platform Administrator provides access to Command Line Interface (CLI), Cisco Unified Operating System Administration, and Disaster Recovery System (DRS). Do the following steps to configure voice messaging in an organization: 1. Customizing the user templates for personalized user accounts. 2. Importing users through LDAP and Cisco Unified CM. 3. Synchronizing the Cisco Unified CM imported end users. 4. Defining the class of service for users with or without mailboxes. 5. Enabling HTML Notification for users See the following sections to understand the importance of voice messaging components: • User Templates and User Accounts: A user template is a way to apply configurations to a new user. The user template consists of the authentication rules, class of services, schedules, and a number of other configuration options and settings. If you change the template in any way, the users already created based on this template are not affected. However, new users that are created based on this template adopt all new changes that were made to the template. By default, you have two user templates, Administrator Template and Voicemail User Template. You can also create your own customized user templates. With Unity Connection, the administrator can configure the users with mailboxes and without mailboxes. The default application administrator user that cannot send, receive, or forward voice message is an example of user without mailbox, and is created using the administrator template. While the users with mailbox that can send, receive, and forward messages to other users using phones or web clients are based on voicemail user template. Users can also send video greetings to other voicemail users. For more information on user templates and settings, see the Call Management, on page 79 chapter. • Creating Users: You can either manually add users or import them from the LDAP directory or Cisco Unified CM configured AXL server on the Cisco Unity Connection Administration page.You can also use Bulk Administration Tool (BAT) to create users with and without mailbox. For more information on creating users, see the Users, on page 37 chapter. • Class of Service and Membership status: Class of service (COS) is a parameter that defines the limits and permissions for using Unity Connection. COS can be configured for users with mailbox and controls the user access to various features and applications such as, message length and using IMAP capability. You can customize the way COS handles the various options by editing or creating a new COS depending on your business needs. For more information on class of service, see the Class of Service, on page 20 section. You can modify class of service membership status for individual user accounts to restrict access for various features using default COS defined during installation. For more information on class of service and class of service membership, see the User Attributes, on page 19 chapter. • Distribution List: A distribution list is a systematic way to group multiple users in Unity Connection that allows to send and receive voice messages to users that need the same type of information. For more information on distribution lists, see the System Distribution List, on page 55 chapter. • Contacts: Contacts are the users that frequently communicate with Unity Connection users. The contacts are part of voice messaging system with voice mailbox account other than the Unity Connection server. System Administration Guide 7 Introduction Configuring Voice Messaging for Each User
