Oops. Should be:

phoneregex = /
   ^        # Beginning of string
   \d{3,3}  # starts with three digits
   \-*      # ...followed by an optional dash
   \d{3,3}  # ...followed by three more digits
   \-*      # ...followed by an optional dash
   \d{4,4}  # ...followed by four digits
   $        # end of string
/x

Well, anyway, you get the idea.
