Let it go to voicemail.

Female Robo Voice: "Revenue Services. The reason of this call is to inform you that the IRS is filing a lawsuit against you. To get more information about this case file, please call immediately on our department number 713-922-6479. I repeat, 713-922-6479. Thank you."

Voicemail states that the IRS has filed a lawsuit against me and to call back the number for more information.

SPAM!

"The IRS won’t call out of the blue to ask for payment, won’t demand a specific form of payment and won’t leave a message threatening to sue you if you don’t pay right away, the Federal Trade Commission advises."

This person called my mother and claimed that she is going to be sued by the IRS.  They have a service to make it go away.  This is a scammer.

Do consider getting a call blocking device or phone.. You can google them and many are around $40.00 or so.If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.
