Who called from 3128091458

Received half ring on 12/27/14 @ 4:25 CST. I'm glad I googled first. Those telemarketers are just waiting for some poor sucker to call back. Then you windup in the constant calls. Not this sucker.

Same thing from today, glad I looked it up too.

I got a call from this number and answered it, no voice or anything when I picked up. Should I be worried?

Received a call  on my cell from 312-809-1458. at 8:15 PM Pacific time. It did not even ring just left a missed call tone. Did not call back. I am on the west coast and have no one in Chicago that would call me.

Same thing. Rang once. Know a few people in Illinois but glad I checked.
