Write an AGI script that expects a phone number as its parameter, performs a 
database lookup on the number and sets some channel variables with the 
caller's name and whether or not they are blacklisted.  You probably need only 
one table, really; use VARCHAR() fields for the number and name and something 
like a TINYINT(1) for indicating whether or not the number is blacklisted.  
After the script exits, the dialplan will see any variables it set.  So you 
can do something like this;

exten => s,1,Set(from=${CALLERID(num)})
exten => s,n,(Incoming call from ${from})
exten => s,n,AGI(lookup_caller.agi,${from})
; /var/lib/asterisk/agi-bin/lookup_caller.agi sets variables `blocked` to true
; if the caller is blocked, and `callername` to the caller's name
exten => s,n,GotoIf(${blocked}?unwelcome:permitted)
exten => s,n(permitted),NoOp(This call is allowed)
exten => s,n,Set(CALLERID(name)=${callername})
; we can maybe do something else funky with callername here
exten => s,n,Dial(${ALL_EXTS})
exten => s,n,Hangup()
; tell unwanted callers where to stick that phone
exten => s,n(unwelcome),MP3player(/songs/kevin_bloody_wilson/dicktaphone.mp3)
exten => s,n,Hangup()


I used some simple example code to implement a little daemon on users' 
workstations; which listened on a UDP port, and created system notifications 
informing the user of an incoming call.  As this was all on the inside of a 
firewall, I also included the capability to open up a web page.  The AGI script 
was able not only to notified the workstation adjacent to the phone of the 
incoming call; but if the number was recognised as belonging to a user within 
our system, would bring up their details on screen  (all the work was done 
through a custom web application).
