P.S. According to the information I found, the number is provided by Teleport Communications in Dallas. I tried calling their number (5:15 Dallas time, number is 214-979-0336); the phone rang ten times before I hung up.
Had 3 messages on home voice mail after work. First from 469-327-6040 second two from 469-287-7833 all said same thing IRS filing law suit against but didn't mention anyones name who live here.
