I was expecting a call from a NY number, so answered this on the first ring. The caller immediately hung up. I'm assuming it was a test dial to find an active number.
So, I called back to their number on a blocked, dummy number. It's 100% a scam.
Here's a transcription of the recorded voice mail (done through a synthesized voice):
