not a valid North American phone number

I am experiencing the same problem, even with a fresh installation of D6.6, CCK 2.1, and Phone 2.2 with default options.

add this to the top of phone.module

include_once('./'. drupal_get_path('module', 'phone') .'/phone.ca.inc');

Fixed in 6.2.4

I got the same error for Italians number.
I tried to add:
include_once('./'. drupal_get_path('module', 'phone') .'/phone.ca.inc');
but still get "...is not a valid Italian phone number
Italian phone numbers should only ..."

Btw, why there aren't in phone.module the includes? And isn't written anywhere to include.

I am interested
