I am a telephone tech and had a call from a customer that when her phone rings, her picture freezes and then the thing reboots. Dish sent her another receiver and(722) she says it does the same thing. I did witness this and wondered if anyone knew what might be going on. I know the phone can't cause this by itself and there would be nothing I could do if it did, as the phone line is fine and another receiver(a 222) is fine. Thanks.
