Set any one or more 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 you dial from
Contacts (see "Dialing by Contact Name" on
page 58). A 1 is not automatically entered if you
dial using the keyboard or the Dial Pad. This
option is available only when Dialing from North
America is enabled.
International Prefix: Adds the specified prefix in front of international
phone numbers; in the U.S. and Canada, this prefix is 011. When you
dial, the plus symbol (+) preceding the phone number is replaced by this
prefix.
To 7 digit numbers: Adds a prefix to 7-digit numbers. For example, enter
your own area code to automatically add your area when you dial local
numbers.
To 6/5/4 digit numbers: Adds a prefix to numbers with the specified
number of digits. For example, if all the phone numbers in your office
begin with 555, followed by a 4-digit extension, you can select 4 and
enter 555 as the prefix. When you want to call a colleague, simply enter
the colleague's 4-digit extension. Your device automatically dials 555
plus the 4-digit extension. You can also create contact entries with just
the extension number and then dial the number from your Contacts list.
