Message on phone where caller identified self as Internal Revenue Service, had foreign accent, said I or my attorney should call back immediately, and alleged income tax deficiency.  However, when I called back and asked if I had reached the U.S. Internal Revenue Service the person who answered (who sounded like the same person who left the message) said no and hung up immediately.  I could hear a lot of other calls going on in the background.  Is this some kind of scam?

I just got a call from a person with a foreign accent claiming that he is from IRS and that there was a serious legal case going on against me for tax deficiency.  I asked for details and he said that either I or my attorney should call IRS at (415) 690-1141 and speak to Kenneth Webster who will provide details on my case.  Needless to say, I am not calling this this number...I will wait for IRS to contact me in writing before I consider doing anything.

I got a call as well, saying that I or my lawyer should call Kenneth Baxter at 415 690 1141...
Caller ID identified the caller as a VoIP caller.

Sounds like the phone scam described by IRS:
