Hmm..
you'll probably need to implement TAPI, which I'm no VB pro (or even a noob), but I can't see it being AT ALL easy via VB. (Even for the most simplest TAPI programs.. It's not easy)

I recommend using Java; via  JTAPI.
Check out: http://java.sun.com/products/jtapi/

This isn't an easy project though. Unless you have the money to purchase a service that already does this; you're going to need to find someone that is a great programmer and willing.

So, until then; good luck! :o)

By the way, incase you're wondering; TAPI = Telephony API (API = Application Program Interface)..
And thus, JTAPI = Java TAPI ....  You know :o)

For more info on these words (or any other IT jargon) check out: www.webopedia.com

To detect the buttons being pressed you need DTMF tone detection (DTMF (Dual Tone Multi Frequency) are specific frequency tones generated by phones). Here's a component I found that should be able to do this (though I haven't tried it):

TAPI can be implemented in VB, as it's part of Microsofts standard libraries. Try looking at:

hope this helps
