Well I'd like to help if I can!

In that case I'd be willing to test anything, if it would be usefull...

No I mean -D! From the man page:
-D print DTMF return code on stdout (for use in shell
scripts). zplay will quit as soon as a single DTMF
tone (0-9,#,*) or a hangup is detected.
I believe it works properly while recording (-r) but not when playing a file.

Would you be willing to share that information?
I've noticed that binary 0s aren't interpreted as silence by the modem...
When plaing a sound file while waiting for DTMF commands (-C), vgetty/zplay
has to fill the time between the end of the file and the receipt of the #
tone with silence. All 0s doesn't do it: it produces the strangest sound!
Asside from that, the conversion problem and the zplay -D problem, the modem
seems to work OK (after a few hacks...) I'm probably missing a few things,
but how much is there still to be done?
