Who called from 2064519208

went straight to voicemail.  Automated message stating something about this case number and should call back 206-451-9208.  Second call today like this and the first was from a different number

just recieved the same call. Second for me today as well. First was from NC.

Message starts garbled... agree, case number and then repeating the number twice to call back. Just now. Did an area code search; 206 is Seattle, Washington. I'm not calling back.

Solicitation said they were the IRS and had a case filed against me.
