There's a solution a million times simpler than this, which I have explained 100 times in various places, and nobody sees its value. That is, when the caller is "connected" the caller is faced with an audio "captcha". Depending upon the caller's actions, the caller may end up in voice mail, or getting disconnected, or getting the phone to ring for the recipient to answer. You don't need a contacts database for this. You don't need Siri. You don't need a "do not call" registry. The first person who invents this will be an instant billionaire, but apparently nobody wants free billions. I have been trying to promote this solution since 1993.
