I had this problem this week and the tech cam out checked the dish and the problem seems to be gone. However if you reboot the box and swm box and wait about 30 minutes it should come back or atleast it fixed my issue and I had the sam e error codes.
I have Comcast Voice with internet and directv, but for some strange reason caller ID does not work with my HR22-100, but yet the phone works fine.
Could someone shed alittle light on thise for me?
