This is a SCAM trying to make you believe you owe money. The message states it is the IRS. The recording goes on to state that you have to call them and ignoring the call could bring a lawsuit against you. This is a SCAM. The IRS never contacts people by phone with a message like this. Do not call the number back or talk to anyone who claims this. If you truly are concerned, call the IRS directly. You can find out more about scams like this one on the Federal Trade Commission's website: www.ftc.gov
I received the same call from 213-141-5163 and asked to call back at 347-637-6194 regarding a law suit against me. I wonder why FBI, national security or other law enforcement agencies won't go after the owner of these phone numbers. It shouldn't be that hard to find out who they are.
Like many below have reported I saw the number 213 141-5163 show up on my caller ID. I ignored it and my voice mail took a chopped off message from a barely intelligible machine recording. It said "...lawsuit had been filed against you..." and told me to call back 347-637-6194. I did not, but will note that number to give out as mine to all other scammers, including solar, veterans, political, windows, and bogus police/fire charity callers.
