Change your voicemail number
If AT&T changes the phone number for your voicemail system, you need to
change the number on your phone. This is the number your phone dials if
you use any of the shortcuts to access voicemail (see Listen to voicemail
messages).
1 Open Phone .
2 Open the application menu and tap Preferences.
3 By default, under Voicemail Number, your current voicemail number
is highlighted. To change it, simply type the new number. If the current
number is not highlighted, tap the number to highlight it, and then
type the new number.
Use dialing shortcuts
Dialing shortcuts add a prefix at the beginning of a number, so you can dial
an extension instead of the whole number.

2 Open the application menu and tap Preferences.
3 Under Dialing Shortcuts, tap Add new number.

When I Dial: Tap this field and select the number of digits you need to
enter to have your phone add a dialing shortcut.
Use This Dialing Prefix: Enter the prefix to be added at the beginning
of the dialed number. The combination of prefix and digits you enter
must add up to a complete phone number.

Example: A complete phone number in your company’s phone system has
11 numbers, for example, 1-408-555-1122. When dialing from a phone that’s
part of the system, you need to dial only the last five digits (51122). When
you create a dialing shortcut on your phone, you select “5 digit numbers” for
When I Dial and enter “140855” in Use This Dialing Prefix. So when you
dial your co-worker’s five-digit extension (51122), your phone automatically
dials the whole number: 1-408-555-1122.
