I just played with that a little, but it doesn't seem to do anything as far
as voicemail is concerned.  Maybe I'm missing something.  It'd be really
nice if there were a way to get voicemail (and other apps, like Directory())
to properly interpret this.

My phone system doesn't give a busy after a hangup, just a 'D' followed by
silence, so right now I'm coping by setting "maxsilence=5" and "review=no"
in my voicemail.conf.  Not ideal, but it works.  I've considered trying to
hack the voicemail source code to handle the 'D', but I haven't really dug
into it.
