It will reject calls (either dump straight to voicemail or auto-answer and hang up on the call) and reply to texts from blocked numbers too with your own "custom" message.

Subject: Attack against Microsoft scheme puts hundreds of crypto apps at risk Message-ID: <p062408a3cc3e7bbac44f@[]> Attack against Microsoft scheme puts hundreds of crypto apps at risk Cloud-based service requires an average of 12 hours to decrypt VPN traffic. by Dan Goodin July 31 2012 Ars Technica Researchers have devised an attack against a Microsoft-developed authentication scheme that makes it trivial to break the encryption used by hundreds of anonymity and security services, including the iPredator virtual private network offered to users of The Pirate Bay. The attack, unveiled by Moxie Marlinspike and David Hulton, takes on average just 12 hours to recover the secret key that iPredator and more than 100 other VPN and wireless products use to encrypt sensitive data. The technique, which has been folded into Marlinspike's CloudCracker service, exploits weaknesses in version 2 of a Microsoft technology known as MS-CHAP, short for Microsoft challenge-handshake authentication protocol. It's widely used to log users into VPN and WPA2 networks and is built into a variety of operating systems, including Windows and Ubuntu. ... http://arstechnica.com/security/2012/07/broken-microsoft-sheme-exposes-traffic/

Subject: FCC to Verizon: Don't block tethering apps. Verizon settles for $1.25M Message-ID: <p062408a9cc3eeecf495a@[]> FCC to Verizon: Don't block tethering apps. Verizon settles for $1.25M BY Stacey Higginbotham Jul 31, 2012 The FCC has come to a settlement with Verizon Wireless that will allow customers of the nation's largest wireless network to use tethering apps from the Android market, and thus circumvent the $20 monthly fee Verizon charges for using a phone as a mobile hot spot. Verizon customers will soon have the option of downloading Android apps that let them turn their phone into a mobile hotspot -apps that Verizon blocked initially because it didn't want customers circumventing its $20 a month mobile hot spot fee. The FCC has determined that nation's largest wireless carrier was in the wrong in this situation because it had purchased spectrum back in 2008 that required Verizon to allow open access to its network. ... http://gigaom.com/mobile/fcc-tells-verizon-you-cant-block-tethering-apps-verizon-settles-for-1-25m/

Back in the nineties I had a 28.8kb ISA faxmodem which came with telephony software (I think it was Sierra somethingorother). It was intended for business use, but I quickly adapted it to my POTS service, and used it to screen incoming calls before they were sent to the actual phone. Of course this only worked when the computer was on, but since most all of the automated dialers at the time called out in the afternoon and evening, it worked well enough. Jon
