Farsight currently always queues tones (we enforce minimum lenghts and
intertones delays) and doesn't have a concept of Stop NOW (stop is just a
message thats also queued).

Feedback is not a farsight issue. That said, with the dtmfsrc element, it is
trivial to produce DTMF sounds with a simple GStreamer pipeline like "dtmfsrc !
autoaudiosink" then then just send events to it.
