This is a scam number. Part of the IRS scam that has become common. They, Officer Paul Jordan (yeah right), called this morning and immediately started with the line "the IRS is suing you... we know where you live... blah blah blah..." very threatening.
I put "debt collector" since there is no choice for scams.
Bottom line, don't answer, and don't call back. All false. Good luck to all!
