Google Voice has the following Known Issues:
Voice restricts calling premium rate numbers
Voice blocks calls to premium rate numbers that charge callers added cost not related to long-distance calling (for example, U.S. numbers starting with 900).
Workaround: Use the native dialer app on a mobile phone or other phone service to make these calls.
Changes to area codes in France
France no longer has 400+ local area codes for Google Voice. 01-05 codes are now used in mainland France, similar to 09 codes. This change may impact the availability of phone numbers of specific area codes.
Workaround: If you're acquiring a Voice number for a French location, pick one within the 01-05 area codes.
