This is probably not new to many, but may help the newer customers. Got a call recently from an unknown number: Phone identified as "unknown". Dish rep wanted to do an audit of equipment: Receiver numbers, software version for all receivers. The whole thing seems quite rude, like they suspect that since you are not hooked up to a phone line, you must be "moving receivers from one location to another" which is not permitted. Apparently sending them $100 a month is not enough and you can expect these audits every six months or so. I would suggest you don't answer this "unknown" call if you want to avoid this invasion.:
