Unavailable number called but when I called the number back, it's recording said it was not a working number. I'm receiving a call like this all the time. I start writing it down, the date, & time. Oh, when I answer it said also, your the only person on conference. What is this call ? The call that I received is from our home phone.
Lately have been getting a lot of hang up calls from various numbers; this is just one of them. I say "Hello", but no one responds then they hang up. It seems like it is some kind of marketing company.
