Abbreviated Dialing supports the following types of lists:

• Personal lists

  Use personal lists for users who need their own set of stored numbers. You determine which users have access to a personal list and the size of each list. Either you or the user can assign telephone numbers to personal lists. A personal list is created automatically when you assign the list to an individual telephone. Each user can have as many as three personal lists. You can assign a personal list to an attendant with a data module.

• Group lists

  You can define group lists for groups or departments where members of the group must frequently dial the same numbers. You determine which users have access to group lists. Each user can have access to three group lists. You can program the list, or you can designate a user in each group to program the list. Specify this designated user on the Abbreviated Dialing Group List screen.

• System lists

  You can define one system list for the entire organization. Most administrators assign this list to each telephone, and allow everyone in the organization to use the list. If you allow everyone to use the system list, include only numbers that anyone in your organization has permission to call. For example, you might want to add an emergency telephone number or telephone numbers for other office locations to this list.

  The system list can contain up to 100 entries, and can be changed by a system administrator. An administrator can also customize the button labels displayed on Avaya 2420 and Avaya 4620 telephone sets for these system-list entries.

• Enhanced lists

  You can use enhanced lists for telephone users, data-terminal users, and attendants who need more list entries than the number of entries allowed in group-number and system-number lists. Two enhanced-number lists are allowed per system, in addition to the system-number list. The enhanced list can contain any number or dial-access code.You administer the enhanced lists and determine which users can access the lists.
