Before I answer my phone, I always check my Caller I.D. screen first. If my Caller I.D. does not identify the caller or says that the call is from ‘Private Caller’, ‘Unknown Name’, ‘Blocked Number’, ‘Unavailable’, ‘Toll Free Number’, ‘Out of Area’, etc.; I will not answer the call. If you are calling me from a telephone that does not identify you or if you have Caller I.D. blocking, just leave a message on my voice mail. Do not hang up and call me back later. That won’t do any good. I check my messages frequently, and I will reply to legitimate voice mail messages. I am sorry if this seems rude, but I get a lot of robocalls and calls from scammers, and this is the only way I can control the problem.
You should do the same thing that I do about this. When you answer a robocall, you are telling the computer that called you 2 things: 1. Your phone number is active and 2. You answer robocalls. Doing that just gets your name put on sucker lists, and crooks sell their sucker lists to other crooks!
