Received another call to our land line tonight (28 Feb 2017, 6:54 pm, Central Time.) Caller ID: LADUE MO. This time I answered. After my 1st "hello" I heard a female voice but couldn't understand what she said. I repeated "hello" and the woman on the other end said, "I'm sorry; I have the wrong number." I replied "OK" and we both hung up. I'll see if we get a call from this number again before I block it.
