Got a call from this number as well.  Not the first time, did not answer, unfamiliar number.  Although search results indicate it could be from out of the country or telemarketing  of some kind.

It's spam....someone elsewhere said ......"Said they were the IRS, I told the middle eastern man to put someone on the phone who speaks proper English and he got mad and started cursing me out cause I told him the IRS doesn't do phone calls."
