[Asterisk-Users] Complicated Dialing plan routing

[Jan Saell]

This is similarly to what you need to do when you have a real international 
dialing system.

What you should do is, regardless of what the customer does dial, you 
should expand this number to a full 10 digits dial string (in the US) or 
the ITU standard in non us countries with 00+country.. and 0+area_code, and 
the use that as the phonenumber to dial. Put the different areas customer's 
in one context for each prefix and use a macro to expand it.

Then put all outgoing calls in another context and there you can use 
whildcards or full number for dialing numbers.
