I think it's all a matter of personal taste.  I think the logic for "add to
DNC" is extremely trivial and would be more complicated with an AGI.  You
have your prompt playback/read, if they hit "1", head to the queue, if they
hit "2", it's a single dialplan line to put the info into the database and
then one more like to Playback a nice "Goodbye" message.  You also add one
additional line before calling out in that case - one query for the
national DNC and one for the "internal" DNC, or you can get really fancy
and setup your table with an extra column that denotes "national" or
"internal".  While you're add it, throw in that extra column for "next call

All that being said, you would probably be better off pre-processing before
sending the phone numbers to the PBX so you've already scrubbed the call
list to only people not on a DNC list and within the scheduled call-back
time.  That way you save the checks for each call outbound and only have
the code for adding people to the DNC and scheduling the next call, though
it still could be done either way (though in the case of not
pre-processing, you're getting closer to making Asterisk into a dialer
system and then you can get into fancy legal issues about using an
"autodialer" when you accidentally call someone who doesn't want to be
called and they complain (dependant on jurisdiction).
