Got a call today from 229-231-3342. We did not pick up the call, allowed a message to be left on our answering machine. Intense sounding male voice with an accent. He didn't specify who the call was for, no company or agency name was left, just a threatening message and a return call number (tried to call to threaten them in return; no ring, just a quick busy signal). Recognized it as a scam but wanted to add our info to the rest. We got a couple of similar calls last year and reported them.

Must be scam - tries to scare you about the Treasury dept and being brought up in front of a judge - "he" with an accent, left message on the answering machine. Returned call to no answer.
