Also known as DID service or called number information at various times. 
You can have analog copper pots lines configured to send that information. 
I don't know if Asterisk supports it. Anyone?

Going to isdn gives you a cleaner and more feature rich signalling. I 
guess whether it is a viable option depends on the price your local
