I think this number is associated with another number.  That number is 806-686-2565 and is out of Lubbock, TX.  281-397-3423 is in Bammel, or Brammel, TX.  Both numbers called after 9:00 am on 5/24/16.  After the third call from the 281 number, it never hung up but had a continuous annoying tapping sound.  I did not hang up my phone.  It will be interesting to see how long that goes on!
