In case you're not already aware of it, the GTA04 list is discussing
this.

I did some DTMF experiments with oFono and got strange results which I
don't understand yet.  I haven't yet rechecked, but I think this is what
happened:

- With Radek's gta04-gsm-voice-routing program running (and in a call),
  the oFono SendTones() call appeared to do nothing.  I think the log
  showed either that the +VTS command was not sent to the modem, or that
  there was no response.

- In another call, _without_ gta04-gsm-voice-routing running, the
  SendTones() call generated the expected tone.

Just in case that suggests anything...
