Hi i had an idea for a program and wanted to know if anyone knew of a way that this might be possible.

What i wanted is basicly a program that answers incomming phone calls, however i want to know if its possible to grab the incomming calls number,(ie the number of the person who rang. like caller id does) then what i wanted to do was to use that number and look up the details of that person in a database and bring their details onto the screen.

any help/idea from ppl with past experience or similar idea would be really great. thanks in advance,
