You can activate a spy on the channel and feed the audio from the frames 
into the speech recognition engine, and read the result. You can then 
inject DTMF frames into the channel which will be received by the 
application ... in theory.

The nifty thing about the speech recognition API is that it doesn't care 
about channels, it just wants audio - so that's what you give it :)
