I have a really weird DSL filter problem. I have SBC DSL for almost two years and I just started to have this problem two days ago. The problem is : whenever the DSL filter is connected to the jack (no matter in the living room, kitchen or bedrooms), all my phones stop working. I could not dial out and no incoming call is possible. My DSL/internet is still working fine. I did a quick test with unplugging the DSL filter in the living room. Then all my phones worked again. I replaced that DSL filter and installed another one, then the phones were ok for a while (maybe couple hours). However, in couple hours it is back to the original situation. It is really frustrating! I still have another (the last) new DSL filter. I am kind of afraid that the jack might somehow damage my filter. Any ideas? Thanks a lot.
