I'm aware of the Vocally3 Infinity box, but it's about $240. I have a Kyocera Oystr that has the same recognition/dialing capabilities and it only cost me ten bucks!

So, I'm wondering about the prospects of using a cell phone's processor with an external DTMF dialer (e.g., an NTE1690 and a PIC).

Any schematics floating around on the net? Has this ever been attempted? Much Googling yielded nothing.

Thanks..
