I just put out a inquiry on this just a few days ago and was also told it can't be done. I made some mp3 files of the various DTMF sequences I wanted - which play nicely when I press the buttons on my app - but it doesn't go out to the other end. You'd think this would be possible. Several years ago, I tried inserting DTMF via the headset jack of a conventional cell phone, but the vocoder mangled it such that it couldn't be detected at the other end. - Brian
