I got one of the calls from the 415-506-2392.  Once I heard the message, I knew it was scam.  I called the number and got some guy on the line (with an accent) who hung up on me twice once I started asking questions about who he was and if he could provide some government identification.  When I called back again,  I asked to speak with "Julie Smith" who left the original message telling me to call right away because the issue was "time sensitive," and if I didn't call back, they would take action against me.  But I was told Julie wasn't available because "she fell down from the first floor and taken to the hospital because she was seriously injured."  

Seriously!  That is about the dumbest story I've ever heard. These scammers are stupid beyond belief.  (By the way, the Julie Smith message is a computer generated voice, definitely not real!)

I've reported this to the IRS Inspector General's office.  I hope they are arrested soon for pretending to be federal government officials.

The name says Navato on the caller I.D.  This is the third phone call saying I owe the IRS and I need to call their number.  Never having a pen on hand to take their number, I just called the I.D. number on the phone.  It goes to a voicemail.  Obvious prank to get information.  I hope nobody falls for this.  I am sure if the IRS wanted me, they would find me, and it would not be by a phone call.

Got two calls from this number claiming that "Julie Smith" is from the IRS.  Please stop these scammers.

I also received a voicemail from 415-506-2392.  Most of the message was cut off (didn't hear that it was the IRS)  but it did say this was time sensitive and that I should return the call to avoid further action. I am of course not returning their call, but it is consistent with the other's messages and clearly a scam.

They  called me and said it was time sensitive ,i called back and left message ,then called back later and a guy answered ,then hung up on me when I questioned him. Who can we call to report this activity.
