Who called from 5032018937

Just got a call from this number.  No idea who it is.  Must be some kind of spam.

I received a call from this number. When I answered it there was no-one on the other end.  I called it back; the phone rang several times, until lastly the Sprint automated-operator said that they were unable to complete the call.  No other re-engagements have occurred yet.

DOL!!!

240pm on the east coast.  Don't know anyone in Oregon so I didn't answer it.
Could be, someone mining for 'good' cell phone numbers.
I am on the Do Not Call list.....
My best bet, it is a robo call.

I'm in NY got a call at 1:42 pm from this number as a Portland Oregon call.  Showed up as missed call and no message.  Not returning call.
