Left a voicemail in artificial text-to-voice - They claim to be from Internal Revenue Services (note misspelling of Service).  The voice mail states "The reason that this call is to inform you that the IRS is filing lawsuit against you.  To get more information about this case file please call our department number 503-558-5187..."  This is a SCAM, block the number.  Do not give them any personal information. Do not call them back.
