I'm working on something that could be usefull for this. It's a PHP
AGI that route the call based on the caller ID. When a call comes in,
you call this AGI which query a MySQL table and look for this caller
ID. If it finds it, it execute the defined steps one after the other.

The table as 6 fields (for now) : call_id_num, step, action, option1,
option2, option3

Example 1 : Someone you don`t want to answer to. You put something
like this in the table
5552222,1,Hangup

Example 2 : Your mother in law, send her to voicemail :)
5553333,1,Answer
5553333,2,Voicemail,u7001

Example 3 : Someone you want to know that you don't want him to call you
5554444,1,Answer
5554444,2,Playback,please-dont-call-here-again
5554444,3,Hangup

Example 4 : Your mistress, ring your phone directly
5556666,1,Answer
5556666,2,Dial,IAX,7001

The action I have in the script so far are these :
- V : send to voicemail 'option1'
- D : dial option1/option2
- P : playback sound 'option1'
- H : hangup
- A : Answer
- G : Goto option1,option2,option3

The next step will be to make a PHP page that will be used to build
the rules with simple choice from dropbox.

It's still in Alpha stage, but if it can help you get rid of those
annoying calls, I'll be glad to share it with you.

I think this could be extended to make pretty smart CallerID based routing.
