"California City, CA" on caller ID. Automated message on voicemail about a nonspecified lawsuit

"IRS" scammer warning of potential lawsuit

What are they trying to do???  Is there a phone charge if I call back this #?

What are they trying to do?  They are trying to scare people into paying them money for bogus tax debt.  More information here, from the real IRS:

Called this # back and I told them  they are a scammer from the IRS.  He had an Oriental accent and told me they are not a scammer.
Bunch of junk.
