5. I just ordered a call blocker from Amazon

I've been getting mysterious calls, too. Mine show "spam" in the caller ID! Then there's no one there when I answer. I used the "call back" function and got the message that that number was not in service for most of them; on one of them a person answered and asked if I wanted to be removed from their calling list, and I said yes.

I heard somewhere that these calls were sort of like phishing, robocalling in numerical order to see which numbers actually belong to a phone. Then lists of phone numbers can be sold to marketers. I also heard that house thieves will call just to see if anyone's home.

My phone has a call block function which can store up to 250 calls, and that does get filled up periodically. With the call blocker I ordered, I can store 1500 numbers, and I can block calls from the same area code counting as one number, like 888. If your phone service offers caller ID you might want to invest in a call blocker.
