[Asterisk-Users] All non US 48 area codes?

[voiplist]

Is there a list somewhere or a way to find the following:

1- All non US 48 area codes which can be dialed as 1+10
2- All strange area codes which are used for premium services such as
900-XXX-XXXX
3- Anything else that should be restricted if one was to restrict all
calls to US 48 only

I have found many list but it's tough looking at the entire list of
area codes and pulling out each of them one at a time.

Thanks!
