[arm-allstar] full duplex radioless node

[B Harvey]

Doug,

   Of course. I should have clarified that in my question. Well, it sounds
easy. Hopefully it will turn out to be when I set everything up. On a
related note, is it possible to redirect the local audio (audio from the
mic) so that it is played through the other, unused channel of the sound
FOB? This side could be "volume down" in most circumstances but only turned
up for testing or other unique circumstances?
