Got a call at 9:02 am and 10:58 am today.  First part of the message is cut off; phone number to call back is repeated clearly twice.  Definitely a robo call.  There was no clear identification of the caller.  A search for the owner of the number shows it is private, which certainly would not be true of a governmental agency.  The search on white pages also notes this number as a potential scam.

Left several messages on land line from the "court house" I called back from my cell answered as IRS. I said "realy IRS you left a message saying you were the court house now you are the IRS? He asked if he could ask who was speaking and I said no, and he hung up. I called back and the number was busy.

"IRS Calling about a lawsuit"

Left several messages on our land line from the county court house or legal matter and to call back. I called back from my line and answered. Said there was a tax issue, then went into a long message saying all the things they were going to charge me. Gave a name as IRS officer and badge number. Was very hard to understand. Then asked why I asked for a name again. Call from NY

Called 3 times today with robo voice that drops a preposition around "courthouse" part.  I did not write down the return call number, so if someone has it, could they please post it.  The calling number was 347 983 0706.
