Before I answer my telephone, I always check the Caller I.D. screen first. If the screen does not show the name of the caller and his phone number, I screen incoming calls, but I will not answer the phone until I know who is calling. If my Caller I.D. says that a call is from: ‘Private Caller’, ‘Out of Area’, ‘Unknown Name’, ‘Incoming Call’, ‘Toll Free Caller’, ‘Name Not Found,’ or ‘Blocked’; I will not answer the call at all. If you are calling me from a telephone that does not identify you as the caller, just leave a message. I check my messages several times a day. I am sorry if this sounds rude or discourteous, but I get a lot of phone robocalls from phony charities andcrooks, and this is the only way I can get control over this problem. When you get a robocall and you answer your phone, the computer that called you will make a note of the fact that you answered the phone. Then they know that your phone number is live and that you answer your calls. That gets your phone number placed on their sucker list, which they then sell to other phony charities and crooks.
