Let's see how that would work with my phone number:

+31 10 75 01888 991
|   |  |  |     |
|   |  |  |      extension
|   |  |   number
|   |   prefix
|    area code
  country code

And this is even shorter then the maximum allowed length for a 
phone numer (15 digits according to ITU-T E164).

Typically I store telephone numbers in a domain with the 
following definition:
CREATE DOMAIN phonenumber AS VARCHAR(20)
        CHECK (VALUE LIKE '+_% _% _%');
