Well, MikeJ and anthm added RBS signaling support some time back. I could
get RBS to work in that I got all green lights and I could see the A and B
bits flipping up and down when I called a channel, but OpenZAP didn't
actually have the meanings of those A and B bits programmed in the
signaling. I hope that makes sense.  Anyway, it is supposed to be there now
but I don't know that anyone has actually tried it yet. I haven't.
Definitely hop on #openzap and confirm with those guys if you're having
trouble getting set up. We'll get it documented once we iron out the
particulars.
