You can still use the dialplan with the DB func to check incoming 
CID info. Also, the Dial() app has several options for call screening
and 
privacy; these would be performed when dialing your extension.

You can have Dial keep a DB of callers, and remember whether to always
just patch them right thru, play them a polite "go away and don't come
back",
or send them off to torture scripts, or just route them straight to VM.
And, Dial() will ask you what you want to do, on the first call. Read
thru the Dial doc you get with "core show application dial". There's
an option to store an intro from each caller, where it records in  a
sound file, who they say they are. I have several hundreds of these, and
play them as the
call comes in, so we know who's calling without having to run to a CID
display.
For those who have poor to no vision, this can be a cool feature.
