Not sure if it is the same thing, but I had the middle of the night calls from random numbers for a while. But it also happens during the day. What I discovered is some scam going on where somebody “shadows’ you phone number. There is some program or tool in use that allows someone to call you and your caller ID will show a number, but it won’t be their real number. If you were to call them back, it would go to the number they used, not to the person actually calling. The person you reach will never have called you. I even got a call from my phone number one night. I’m not exactly what the scam is…something about if you answer they get some data from your phone I think.
