You can't, phone numbers are more complex then that. You could use
\d{3}-\d{3}-\d{4} to match that basic pattern for all numbers though.

Rick-
It is generally accepted that you should use single quotes whenever possible. I
only use double quotes when writing SQL queries (so I don't have to continually
escape them for the single quotes) and when I need to output control characters
like "\r" or "\n".
It would be considered "best practice" to make consistent use of them, but it
wouldn't be something I would loose sleep over.
