Call came in on our landline at 134P CDT, Caller ID showed "Wireless Caller". 830-279 NPA-NXX is a number group assigned to Southwestern Bell (now AT&T) in Uvalde, TX. A digital female voice left a long voicemail about the "IRS filing is a lawsuit.....". The IRS never emails or calls, they always send a letter first, so this is just another of a long line of SCAM calls. The number is now blocked.
