I am tired of getting these anonymous phone calls where if you try to return a call either phone is nit is not a legitimate phone number or the phone has been disconnected. How can AT&T allow phone calls of this nature to be placed on airlines how can any one place a phone call from a number that is not a legitimate number or how on a masking the number so that you don't get a legitimate number on your caller ID. My house soul averages 5 phone calls either 800 numbers trying to scam someone or anonymous numbers what date that don't answer or tape recorder phones and I cannot believe AT&T can do nothing to stop these people who from what I read each of these organizations can make two million phone calls per day.
