404-934-7046

Call blocker might be of some help.  Also don't pick up on numbers you do not recognize, or where there are caller IDs that seem odd.  Or where there is no caller ID.  There’s  no way to stop the calls from being initiated. Calls originate in India and Pakistan and they spoof local numbers.

No one on this site is calling you.  Invest in a call blocker and do not pick up on numbers you do not recognize.

Got two calls from this number today. First time it came up caller ID said it was from Romania and gave +40 49347046 as the number.Left partial message both times saying I was being sued by IRS. Did not call back

Automate voice message says this is IRS filing lawsuit against me , call back

called two times on 12-2-15.  Heard message and didn't answer.  Had received previous calls and knew it was a scam.  Also don't answer if someone says they are calling from Microsoft!!!

They left a message stating that the IRS had filed a lawsuit against me and that I needed to call them back.  The IRS sends letters - they don't call. Scam.

leaving messages that they are from   IRS,  and I need to call them back. Let them Waite for 100 years.

Official IRS Government site detailing this scam and providing links to report it:
