    Cell phone dtmf generator/decoder

    Hi i am currently working on something similar but i am having a slight problem getting any output from the dtmf. I do how ever get an output on pin 16 every time i press a key on my cellphone but no output on pin 11-15. Could the problem be the phone I'm using?
