Whenever I get a call from a number I don't recognize, I just pick up and listen without saying anything. If there's a human on the other end, they will usually say something at which time I will respond. If there's no sound including background noise, I know it's a robocall. A robocall is what this number is associated with.
A woman asked for me **** by name. I asked who is calling? She asked is this ****? I replied, who is calling? She said, 'Thank you for your time.' And hung up. My number is on the National Do Not Call list and apparently some people think it is fine to violate my wishes. I will not identify myself to someone until I know whether or not I can identify if I know the caller.
