I recently installed a router for Dish Satellite and it seems to have caused a failure to telephone lines. The DSL line stills works I have outside phone connection from the telephone connection point but no phones work on the inside of the house. I am using a hand telephone that is working. I have tried removing all telephones and then reconnecting but no avail. Telephone company says problem is inside of the house. I believe it had something to do with electrical router I had hooked up. It is disconnected. Help!
