I got a call from this number yesterday. So, it looks like it was a scam call.
I've been getting these types of calls more frequently for the past few months and I have no idea why. I pretty much never give out my number and don't answer the calls when I get them. Despite that, I went from getting a robo call once or twice every other month to getting at least one call a week.
Received a call from this number on 27 Mar 2017 @~11:55a. Answered but no one there, then the caller hung up. My guess is that these calls are phishing for 'live' cell phones that can then be used for tele-marketing (real & scams). Grrr.
