[android-developers] Re: Send dtmf tone on uplink

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.
