Callers are located in India and Pakistan and they ignore all US laws. There's nothing the US can do and the local governments do little.
Invest in a call blocker and DO NOT pick up on call numbers you do not recognize. Common scam, been around for years.
Called the # back. Super noisy in the background, think i heard a couple of children. I mentioned to the woman that answered, that the whole thing doesn't seem too legitimate. She didn't even challenge me, just said 'ok' and hung up.
Kudos to em though, i listened to the voicemail about my arrest warrant while stoned. Scared the stuffing out of me.
