I get these calls almost daily and I never answer.  We DO use Medco so I am not sure of the validity of the calls, but today I pressed 'talk' to see if I could actually talk to a real person. After about 20 seconds of the robo trying to connect me, it hung up. So since the federal DoNotCall does not seem to work, I am using all of the technology available to combat this caller (and others). My Panasonic phone system has a built-in caller block that you can block the number with only a few keystrokes. That is the best that any of us can do since the government and phone companies are unwilling to help John and Jane Doe in this blatant form of phone and privacy abuse.
