Same number called me too on my Skype Number. I blocked it and was always wonder who the hell this was calling me. Then today another number called me similar 1-931-222-1416. I said hello about 5 times and just hung up on this son of a b***h. I blocked that number too. I did a good and got a name of Mr.Vikas Gupta. Don't know if that is the person or not but it's something suspicious of last 4 numbers as 1401 then 1416. I will investigate some more. He don't want me to hunt him down and bring forces.
Use skype services if you have a internet connection and save money a year. Only 30 dollars for your number for 1 year and 30 dollars for 1 years of access. That's 60 Dollars a year for phone service. Plus you'll need a DLink Skype Adapter to use cordless phones as I do. the model is D-Link DPH-50U. Use skpe and add numbers like this to the "BLOCKED LIST" and they can never call you again. ;) Hope that helps out
