Is there a way to access the call before it hits your phone? I looked briefly, because I'm very passionate about this problem, and couldn't find anything. I don't want to answer the call and wait for someone to enter a pin. I want them to have entered a sufficiently long randomly generated number (spoken to them by some voice generation service) before it even makes my phone send a notification to me.

You might be able to host an instance of Asterisk [0] and set up call forwarding based on the extension [1].

I haven't played with Asterisk before, so I'm not 100% certain.

Learn the lessons of SMTP-based electronic mail. Non-solutions like this just lead to an arms race. And indeed the other side already has a huge in lead this particular arms race. Voice recognition, speech-to-text, and DTMF generation are widely available telephony technologies.
