Recently Verizon has started a new call block program. Not sure this is any better than old version. It will "NOT" block a call where the number and or name is unavailable. The system is suposed to be watching for just this type activity and block it before it gets to your phone. Phone number is registered with government, still get robo calls. I use NoMoRoBo and still get robo calls, at times from the same numbert that has been reported wsometimes weeks before. The problem now, I can't even get numbers to report to NoMoRoBo. So much for new apps!
