DTMF codes instead of "RING" for vgetty ?

This is how it works for data/fax modes but if you put the modem into voice
mode #cls=8 then it should work as I've described.  I've only tried this
with Rockwell based modems so I don't know how a Sportster Voice would
handle it but the Rockwell's all seem consistant.  I guess it's possible
there is a difference between modems sold in the U.S. and those sold
elseware.  If you have a Rockwell based voice modem sitting around could you
give it a try with #CLS=8 before doing an ATA and see if the phone (when
connected to the phone jack of the modem) still works?

I think that all that is required is a hook to an external script in place
of the code that listens for "RING".  Alternativly, maybe if mgetty/vgetty
just sees "RING" it behaves as normal but if it sees 't' it runs a
user/third party geterated script.  The script could return with different
codes to tell vgetty to either:

1  Just go on as normal
2  Answer as voice:fax:data
3  Answer as fax
4  Answer as data
5  etc

Otherwise the script could be responsible for sending signals to the vgetty
process. and vgetty would just do #1 above.

Does any of the above sound reasonable?
