your own area code to automatically add
your area code when you dial local
numbers.

number of digits. 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

and then dial the number from your
