Preferences.
4 Set any of the following options:
Dialing from North America: Formats
phone numbers using North American
conventions (XXX-XXX-XXXX).
Always dial +1 in front of the area
code: Adds a +1 in front of 10-digit
phone numbers. This option is available
only when Dialing from North America
is enabled.
To 7 digit numbers: Adds a prefix to
7-digit numbers. For example, enter
your own area code to automatically add
your area code when you dial local
numbers.
To (6), (5), (4), digit numbers: Adds a
prefix to numbers that are only six, five,
or four numerals long. For example, if all
the phone numbers in your office have
the 408 area code and a 555 exchange,
followed by a 4-digit extension, select 4
and enter the prefix 408555. To call a
colleague, simply dial your colleague’s
4-digit extension; your Treo 680
automatically dials the rest and makes
the call. You can also create contact
entries with just the extension number
and then dial the number from your
Contacts list.
