We get robocalls on our cell phones, even after being on the Do Not Call list. There is no way to get off. Is there a way to recognize a robocall and zap it before it rings?
That would not be difficult. The phone can answer the call and say, ‘If you are real person, press 1 to ring the phone’. If 1 is pressed, ring. If not, hang up.
Hiya app will do it.
