A while back I asked about a device that allows blocking numbers using CID, much like the old Radio Shack CID did. I lost the site address.

If you add your own voice modem and windows computer a program called Phone Tray Free will do the job.. It will handle multiple lines and you can customize the response based on CID number or name. I use it from a home file server that is always on, very little overhead.
I did find the site.
