I know a number of people that use Asterisk & FreePBX as a home privacy manager.
I think it would be great to see a way to catch and be able to set a destination for anonymous CID type calls. (The only present GUI way is to catch them with the Privacy manager.)

The other thing that I think would also be useful would be the ability to set a destination for blacklisted calls and or an extra field to add notes to about the flagged number.
