This is a very difficult task as phone numbers are written differently nearly in each country.
I never get inconsistent results when dialing numbers using the PSTN.
For example, in the US (where mobile phones have the same area codes as landlines, I could dial 1-123-456-7890, or 011-1-123-456-7890 (where 011 is the international dialing prefix in the US and 1 is the international dialing code for the US), 1-123-456-7890 (where 1 is the local dialing prefix in the US) or even 456-7890 (assuming I was in the 123 area code at the time) and get the same results each time.

I've seen some phones that put Q and Z on the 0 key, and some that put Q and Z on the 1 key.

Often there'll be a flag in the ISDN signalling generated by the PBX (or in the network if you're on a steam phone) which tells the network whether the number being dialled is local, national or international.
