Mike Sandman www.sandman.com sells just such an item. I forget what it's called but you should be able to find it on his website.

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. > > Mark > > > > ********************************************************* > * To unsubscribe, e-mail [EMAIL PROTECTED] * > * The KXT-Digest Home Page: http://kxthelp.com/ * > ********************************************************* > > ********************************************************* * To unsubscribe, e-mail [EMAIL PROTECTED] * * The KXT-Digest Home Page: http://kxthelp.com/ * *********************************************************
