It says "Out of Area" on the caller ID. 773 is a Chicago area code. Don't know who this is. I answered, only because I was expecting a call for a delivery notice and thought it may be them, but... silence. Robo no talk-o. No live person. Just silence. I hung up.
Called my cellphone 15 minutes ago at 12:58 pm. Caller ID showed CHICAGO, IL, which is just 30 miles away. No message was left and this is now blocked.
