So to avoid robo calls your going to force friends and family to go through a robotic system to talk to you? Wow!

It's all about getting the system to play back a recognizing the audio signal. It's all about learning everything you can about the phone system and how it works.

I figure if they are going to talk to a machine they may as well talk to the answering machine and leave a message. Typically you can have the incoming call head over the answering machine's speaker so if it is a person you want to talk to you can pick up the receiver before they hang up.

The extra security door on the front of the house isn't a vary good analogy here. More like a padded blanket over a bird cage. You can cover it up to help minimize the anoyance but you also have the option to get rid of the anoying bird all together.

So you'll want the pi to read the caller ID and decide what to do right? We'll you'll need to figure out how the caller ID system works so the pi can read it. Unfortunately not all blocked or unknown numbers are auto dialers. Not to mention that most of these systems spoof the caller id so they look like a valid number but are not. On the plus side if your in the US you can reduce the number of these calls by adding your number to the Do Not Call List.

Also most of these systems have voice recognition (per governemnt regs) and will aknoledge if you tell it to remove you from their list.

How can you automatically tell if a robo call is coming through? I think you need a whole lot more processing power and speed to even do basic voice recognition.
