Well, once you've worked out whether the caller is welcome or not, then you 
need to dial your phone if the caller is allowed; or just play a suitable 
message and then Hangup() if they aren't.

exten => s,1,NoOp(Incoming call from ${CALLERID(num)})
exten => s,2,System(check_ban_db ${CALLERID(num)})
; goes to 3 if system cmd exited OK or 103 if exited non-zero
exten => s,3,Dial(${MY_PHONE})
exten => s,4,Hangup()
; step 103 is where we deal with unwelcome callers
exten => s,103,Playback(f-off)
exten => s,104,Hangup()

You just need to make sure that you have a suitable message saved in 
/var/lib/asterisk/sounds/f-off.wav .
