I think that I'm missing something, here. Mike Sandman carries a number of digit detection products, including some that have serial ports. While they are a bit pricey, you can check them out at: http://www.sandman.com/digit.html. That said, I am still missing a piece of this puzzle. If you are trying to intercept an incoming call, the call will have to be answered before you will be able to listen for digits from the outside caller. At that point, how will you get the answering machine to answer the call?

Does anyone know if a product exists which plugs into a phone line and can then send RS232 to a computer whenever it hears DTMF on the line? I need to find a way for a PC to handle someone entering a string of DTMF digits in order to check the number against a little database. If the number is valid, a relay will close and the call will then be connected to a pre-recorded message. (The line will be answered by a TAM). I would rather not build a DTMF decoder from scratch (I need to make four units in total), but I know that I *could* use a dtmf decoder IC and have it sent its data through to the keyboard. I'm just hoping that a gadget already exists so I do not have to re-invent the wheel.
