Calls to DirecTV each night

[abward]

Nearly every night, there is a 1 or 2 minute call in the logs to DirecTV (8666858469) at about 03:00. I understand that my receiver is probably sending usage stats or something to the mother ship.

Is it doing this each night because it is failing and retrying, or is this normal? I am thinking about unplugging the phone line from the receiver!
