Consistently formatted data is easier to work with, so
I suggest storing the phone numbers without any
non-numeric characters. This would require writing
some application code to extract the numeric
characters, either within the database using a
trigger, or within the client application.
Arguments about whether to store data as a single
string/number or whether to break it up could go
either way. Probably you would want to at least have
a separate field for extension numbers, and if
international numbers are likely to be stored, for
country codes as well.
