Hi, In case anyone missed this. Its already built and its $45 shipped.

DTMF to RS232 DTMF Decoder (part # DTMF232-A)
 Do you need a DTMF decoder with only RS232 output? 
On-board voltage regulator (7 - 18VDC input level) 
Approx. 13mA idle current, 20mA during tone decode/LED lighted 
On-board DB9 female connector 
On-board audio input (RCA) jack 
True RS232 voltages 
Dip selectable 1200/2400/4800/9600 baud rate, 8 bits, no parity, 1 stop bit 
decodes all 16 DTMF tones (0-9, A-D, #, *) 
LED status indicator LED shows when a tone is detected. 
Decoded tones are sent out the serial port as they are decoded. 
accepts line level audio input directly 
in fully assembled form. You supply a case. 
NOTE: There is NO display. This decoder ONLY decodes DTMF tones and sends them out the
serial port 
Assembled and Tested - $40.00 + $5.00 SH (US funds).
