Received recorded message from 206-495-9209, the caller identified herself as Julie Smith from the IRS Hot Line, stressing not to ignore this message and threatening tone at the end of call that we had better take care.  

called and left a message, that it was the IRS hot line and that it was time sensitive. They had been calling for days and I refused to answer when the caller ID says unknown name and unknown number. They had called before 7 a.m. and again at 11.am If the IRS has to contact you they do it by letter. Just another phony scam.
