I had Voom installed on 1/25 (everything went extremely well btw, but I do have to pay extra for running the cables in the crawl space and for mounting the antenna/dish on the chimney). I had 2 receivers, one hooked up to a land line and the other was not. The one that was not hooked up stopped working after several hours; the ota's were ok, but the satellite channels were all gone, with the message Need upgrading.... Soft reboots did not help. I called CSR and she told me that a phone line connection is needed, so I did, and the receiver started working after maybe 1/2 hr after I hooked it up to a phone line. So I am puzzled as to how people can get it to work without the connecting the phone line. BTW, the installer also told me that connecting the phone line is not necessary. The sw version is 7.33.
Since then everything has been perfect operationally (knock on wood). Heck, even the caller ID feature works, which I thought was pretty cool.
One more thing, neither of my TVs have easy access to a phone jack, so I ended up having to use the wireless phone jacks that plugs into electrical outlets (you can buy one from hardware stores). There are a lot of static noises if I try to use a regular phone on the wireless phone jack, but the Voom receivers do not mind apparently.
