Forgive me if this topic has been posted before. I did a quick search and didn't see anything: I've noticed each morning when I get up the my phone line is "in use" meaning that the phone line is active and if anyone were to call me, all they get is a busy signal. The only way I know that our phone line is "in use" is a tiny green light on our answering machine/phone system. It took us about a week to realize that we weren't receiving any phone calls and only when a family member tried to call our home phone and got a busy signal (even though no one was using the phone) that we realized that each day our phone line was busy. I tried troubleshooting everything to narrow the culprit and have determined that its my new Hopper w/Sling. I did by the way, attach a new phone line filter and phone cable to make sure they weren't causing the problem. There is only one electronic device in our home that uses the phone line each night and thats our Hopper w/sling. I also determined that it was the Hopper w/sling because in the middle of the day, the Hw/s had a problem/glitch recognizing my external hard drive so I pushed and held the Power button for a moment to reset everything and guess what? When the Hw/s was done resetting and the signal was gained after several tests etc., our phone line was again "in use". Anyone have any thoughts on this? I also have an ethernet cable running into my Hw/s so is the phone line redundant? Do I have to keep the phone line plugged into my Hw/s? If the only purpose to keep a phone line plugged in is for the Caller ID, then I guess the lesser of the 2 evils is to unplug it since I would rather have a clear phone line than the Caller ID (although its is convenient so see who is call in the TV). Thank you for any help you can offer!
