Hi Folks,

I've been troubles to find a rule/method to correctly identify the telephone
area code of an international number for billing purposes.
I tried to follow RFC specifications (E.164) but I realised that there are a lot
of exceptions to complete an international phone number.
Does anyone have an idea/rule to correctly identify it?

Thanks in advance.
