Phone gets blown up by SPAM calls

Spam, spoof, robocalls still completely out of control- even with nomorobo up and running.  Spoofing numbers has proven to be an effective workaround for the criminal harassment industry.  Is there any way to challenge calls... have the caller key in a number to complete the call?  Would my "Friend in the Digital Age®" consider helping law enforcement find these criminals and bring them to justice... or at very least block calls with inauthentic caller ID info?

The latest robocall shtick is the ID info starts with "V" then a random string of numbers... with the call back number spoofed, of course.  

My phone is useless for incoming calls because of this.
