You're talking about DNIS: Dialled Number Identification Service. 

Some telcos can provide it on some analog services, usually those
described as DID, terminated on Dialogic DID-120 cards, and sold to
answering services run by little old ladies with 4-digit nixie tube
display boxes on the shelf next to the WeCO 300 (and no, to coin a
phrase, I am *not* making this up).

IOW: Yeah, go get ISDN.
