When I Dial: Tap this field and select the number of digits you need to
enter to have your smartphone add a dialing prefix.
Use This Dialing Prefix: Enter the prefix to be added at the beginning

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 smartphone, 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
smartphone automatically dials the whole number: 1-408-555-1122.
