Got a call, they keep calling , no message. Annoying!

They called, but no response when I answer.  Then they hang up.  Agreed annoying!

This caller is SICK! Calls almost daily and stays silent if you answer. Today, I he asked my name and then my wife's. I gave no info and hung up!

It pays to have a smartphone. I create contacts, Scam1, Scam2, .... for all these numbers. More than one scammer number can be added under a contact. I check the option "Send all calls to voicemail" for these contacts. I am never bothered by these calls again as they all go to voicemail and scammers don't leave messages. I see all the attempts as missed calls but the phone doesn't ring. When I have time I delete the missed calls from the log to completely erase the thought of receiving these call.  Have a nice day, good people and scammers.

This stupid [***] called me, I answered and he or she listened for a while, then hung up.  I agree that this caller is sick, probably has phone tourettes or something.  I like the advice of the above person, I created a contact named SCAM and added this phone number as OTHER 1.  I then checked send call directly to voicemail.
