Hi post reader!
For my final year project i am building an interactive voice response system that uses the ICS 8870 for decoding dtmf, rs232 n max 232 for serial communication and 8951 microcontroller for call detector n etc..
It would be very helpful to my cause if anyone could tell me of any such existing small scale ivr implementation... :)
thanxalot
