I received three calls (so far). During the first call, I answered. A female voice asked for "Jason". I told them it was a wrong number.
The second call was at 3:44 AM. I replied with a text message saying "wrong number"
The third call occurred later that day at 3:24 PM.
No response to a call to that number over the Skype network shortly after the third call. I hope it is a cell phone with a battery that I can drain....
