Short answer:
The IRS never initiates a contact via phone.
They always send a snailmail first.

SCAM! I listened all this bul***t and said Go F*** Yourself!

I live in CA, and this woman called me again today from NY and left a voice mail, the same woman with an accent from 2 days ago, saying that I am under Federal Investigation Department about a warranty against me, and the police will come to the physical address to arrest me. So I need to call them back to solve the problem, blah blah blah....She called two days ago with the same voice mail, and I did blocked that number 347-781-4920. and today She comes back with different number to call me. No matter how many times we block them, they will come back and have a new number to keep calling and calling, never ending!!!
