It's bs I'm sure the irs usually corresponds via u.s mail or 800 number

I got a call from this number as well The lady stated she was from the IRS I admit it scared me at first I did my research before I called them back,plus my mother called them herself and got just a regular voicemail, don't believe whoever is calling from this number!!

This company calls and identifies themselves as the IRS not Frontier Communications Northwest Inc.

I received a call from this number. Yesterday they did not leave a voicemail. Today the lady left a voicemail.  She stated she is with a law firm and a law suit has been filed against my name and social security number.  I have never even been to Washington.  She stated that if did not appear at trial a warrant would be filed and I would be arrested.   I called the number back and get a recording that no one is available to take my call.  I left a message that did nor include my name only my phone number.   This has got to be a BIG SCAM and I wonder how many people it has affected.  

The call I got is from a mysterious  Law Firm in Washington
