They called telling me I'm being sued by IRS and to return the call. Of course I never did. I also heard on the news that the IRS would not contact you by phone. They must think people are stupid!
The computer-generated message left on my mobile voicemail is identical (same exact wording, same voice) to several messages since last May EXCEPT each message originates from a DIFFERENT phone number (even different area codes). The message fails to identify a company but urgently requests a return call to the "? department" about my account. I do not answer suspect calls. This one is highly suspect and I believe it is the IRS scam described by other recipients.
