Automated call from a computer generated voice. same as number 213-861-4660. Scam?

Call from "IRS" reporting I had to return their call or my attorney had to

This is a scam.  A recording claims to be the IRS and that you must call them back.  DO NOT call them back.  This is how people hack into your SMS.  Repeat, DO NOT call them back.  If the IRS needs to talk to you they will send you confirmation of any legal concerns about you in the mail on official letterhead..

prerecorded message stating I had to return their call

Got the same call twice on my cell phone yesterday. Twice.
