Does anyone have a suggestion on how to format the phone numbers based on the country's phone number format?

Since the table doesn't show the formatted entry (which really makes no sense), I need to create a formula in Crystal, but isn't there an easier way instead of including each country in the formula? This is where I don't understand Sage and why they don't put the format where the phone fields are.

Does anyone else have this problem?

Thanks

Fabian
