Robocall, female voice about IRS collection. If you call back, you get a garbled internet voip connection to some English speaking Indian/Pakistani/Etc. person, how pretends to be from the IRS. (this number is listed as Washington State, USA). Definitely NOT AMERICAN ENGLISH, even with the fake American name. Block the call and/or report it to the FTC & FCC. THEY NEED A "CALL TYPE" of "IRS COLLECTION SCAM" for this site.
