Rec'd call, it rang through because of an auto-answer feature I use while I work from home. Nobody on the other end. I did not make a peep and hung up promptly. Hopefully the act of connecting doesn't open me up for something bad.
Unusual to see this one displayed as "Baltimore MD" but likely the FOP scam. Endless numbers to call from or spoof and never leave a message. Protecting and serving by phone to cut costs.
