Back in the early 70's, My sister and her young son moved into an old house down in the southern part of the country. As I said, the house was indeed old but, it was only for a year until her husband would complete his military commitment over seas and then would be back home and a civilian once again. So she figured the old house would suit her purpose for a year and besides the owner was asking a very low amount of monthly rent.
My sister noticed that there was no phone in the house and only one phone jack and that was in the living room. She said she had to wait until pay day to get a phone installed. She had an especially busy day at work that day and was very tired when she got home. later that night, she put her son to bed and she went to get ready for bed herself. As she was getting ready to turn in for the night she heard a phone ring. She thought she just imagined it because it only rang once and, she already knew there was no phone in the house. She went to bed and just as she was falling off to sleep she heard a phone ring again. She didn't get much sleep that night because of the sound of a ringing phone. It actually woke her son up and together they searched the entire house for a phone including the basement and attic and there there was no phone to be found.
