I call your phone number.

If no match, "You have reached Name. Press 2 to leave a message.

Ring through on a valid code.
If 0, the call connects to a call center where a live operator
evaluates the call. Who am I? Why am I calling? Do I meet the
plain-English criteria you've established for calls to allow through?
If no, the operator offers to connect me to your voicemail. If yes,
the operator dials you, explains who's calling and asks your
permission to connect the call.

It really doesn't (currently at least -- until robocallers start using
voice recognition to defeat my system) need to be this complicated or
over-engineered.  A simple audio captcha works wonders.

   Hello.  If you are a telemarketer, press 1.  If you want to speak to
   somebody at this number, press 5.

Anyone pressing 1 gets their caller-id added to my blacklist and is
asked to add our number to their do not call list.  In reality all
telemarketers use robocallers so they don't even get that far.

Hi Brian,

I don't want to start an arms race with the spam callers, I want to
end it. That means: jump directly to something they can't easily
defeat.

Regards,
Bill Herrin
