A brief look around shows the following characters also commonly used in 
phone numbers as people actually type them in the US: ' ' (ascii space), 
'.', '-', 'x' (this last in cases like "1-800-123-4567 x235").

This last case in particular is one I would suspect involves a good bit 
of regional variability; I doubt the Latin lowercase 'x' is used 
throughout the world to denote extensions.
