Use the Abbreviated Dialing (AD) feature to reduce the number of digits that you must dial to place a call. Instead of dialing the entire number, you dial a short code to access the number. The system then dials the stored number automatically. You can also assign abbreviated dialing buttons to telephones, so that you press a single button to dial frequently called numbers.

Abbreviated Dialing is sometimes called speed dialing.

You can store telephone numbers in four different types of abbreviated dialing lists:

You can also assign privileged numbers to abbreviated dialing lists. Users can use privileged numbers to place calls to numbers that might otherwise be restricted.

Privileged group-number, system-number, and enhanced-number lists provide access to numbers that usually might be restricted.

The switch type and the version determine which lists are available and how many entries you can have on each list. You can assign up to three AD lists to each user or extension. You can assign any combination of a system list, an enhanced list, and as many as three personal lists or three group lists. The list can also have three group lists. Each entry on an abbreviated dialing list can have as many as 24 characters.
