The A,B,C,D DTMF keys work just fine in function statements -

ABC=status,12

Entering *ABC  gives time of day

Asterisk's "dsp.c" (even the old version in the app_rpt fork, I believe) does indeed already decode them at no additional cost, so I too would have expected them to just come along for the ride.  Does some other part of the system filter them out?

Who cares why -- although I can think of a dozen use cases without even trying hard.  Besides, it costs absolutely nothing when you're already doing the other digits.  Let the man have his tones, I say.
