DO NOT ANSWER AND DO NOT CALL BACK - it's a phishing call probing your number if it's a live number. As soon as you answer, you'll be flooded with calls from other numbers from it's "network."
During last two weeks I got about 50 calls from 603-214-3692 despite the fact my number is on the federal do-not-call list.
calling me non stop. I pick up, they hang up.
