Ditto. Answered with "who is calling?" and got no response.

Me too. A new number amdist a list of spam calls from Texas recently.
Caller ID could be faked but, reported below as it showed up. I'm guessing that it is a voip-originated call and the service came from Vitelity who supplies VOIP phone services.

I answered their call and said hello three times - silence on the other end of the line. Hung up the phone and blocked the number,

Just got a call from this number, Customer Service with no company name and a "man" named Josh. Sounded like a live person but was recorded...trying to give a trip to Disney. Number is now blocked.
