For incoming calls I'd do something like (simplified):
[incoming-calls]
exten => BUSINESS1,1,Dial(SIP/business1)
exten => BUSINESS2,1,Dial(SIP/business2)
...

assuming you got channels that give you that information, e.g. ISDN or
so. Analogue pots won't provide the information which number was
dialled.
Asterisk will match the number that was dialled in the dialplan as the
extension. You might want to put a pattern in in case the number dialled
isn't specifically listed. (e.g. your numbers?)
