I got a call today from the same number and they left a partial pre-recorded voice message. I called them back with my phone number blocked and they refused to identify themselves until I called with the number unblocked. Appears to be, as others have stated, an IRS scam. Doing a little research, I found out that the Treasury Department is treating this as a serious matter and they have set up a yellow highlighted block near the top of their website to report it.
