/mcpAlternate extensions are grouped into two categories: • Administrator-defined alternate extensions-Administrators can add up to 9 alternate extensions. Administrators can view and edit both administrator-defined and user-defined alternate extensions. • User-defined alternate extensions-Users can add up to 10 alternate extensions if they belong to a class of service that allows them to manage user-defined alternate extensions. Users can view administrator-defined alternate extensions if they belong to a class of service that allows them to do so. Class of service settings allow you to determine whether users can view or manage alternate extensions and whether they can use the Unity Connection Messaging Assistant to manage a set of own alternate extensions. Users who belong to a class of service with the Allow Users to Manage Their User-Defined Alternate Extensions option enabled can automatically add alternate extensions.To learn more about this feature, see the System Settings, on page 217 chapter. Using the Custom Keypad Mapping tool in Cisco Unity Connection Administration, you can provide users with the option to edit the alternate extensions from the Preferences menu in the phone interface. When a user selects the option to edit the alternate devices, Unity Connection allows you to list or delete the existing alternate extensions. If the user signs in from a phone number that is not the primary extension or an existing alternate extension or in the Excluded Extensions for Automatically Added Alternate Extensions restriction table, when they select the option to edit the alternate devices, Unity Connection offers to add the phone number as a new alternate extension. For more information on custom keypad mapping, see the Using the Custom Keypad Mapping Tool, on page 268 section. Alternate Extension Custom Settings There are several conversation settings that can be customized for alternate extensions. By default, each alternate extension uses the same settings that have been configured for the primary extension of the user. You can also edit advanced settings, such as conversation volume and message speed for alternate extensions (work phone or mobile phone) from which the user is calling. For example, a user calling from a mobile phone may want to use the voice-recognition input style and not be asked for a PIN. But a user calling from a work phone may want to use the touch tone input style and be required to enter a PIN. Alternate Names Alternate names are different versions of a name than what is listed in the corporate directory. Cisco Unity Connection considers these names when a caller uses voice recognition to place a call. For example, if a caller asks Unity Connection to dial "Mary Jameson," which was the maiden name of Mary Brown, Unity Connection can reference this information and connect the caller to the correct user. In addition to recognizing alternate names when users and outside callers use voice recognition to place a call, Unity Connection recognizes alternate names when callers and users use voice recognition to address voice messages. Alternate names can be created for users, VPIM contacts, administrator-defined contacts, system distribution lists, private lists, and user-defined contacts. While Unity Connection already recognizes hundreds of common shortened names (Bill in place of William, for example), you might want to add another version of an uncommon name, unusual nicknames, or maiden names. You could also use alternate names to add phonetic spellings of hard-to-pronounce names. For example, you could add "Goolay" as an alternate name for the last name "Goulet." From the Cisco PCA, users can edit or change the alternate names and can also create alternate names for customers, suppliers, family members, and friends who are not included in the Unity Connection directory, System Administration Guide 299 User Settings Alternate Extension Custom Settings
