I get at least one call a day on my cell. I do not recognize the number however I answer. I say my name and wait. At the 10 second mark the line is disconnected with nothing from the caller side. I immediately block that number. I just don’t want to be bothered any more.

Doesn't matter that you blocked the call. You just let whoever was testing your phone number that it is indeed a legitimate, in-use phone number. That's why nobody says anything when you answer.

Thanks for the line testing information. However calls are becoming less.
