My phone jacks have spontaneously stopped working. When I moved in to my old house, 2 jacks worked and several others did not. The kitchen jack used to not work. Now the kitchen jack works and the others that used to work do not. There is an alarm system in my house that I have not activated and am not using. I have cut a couple unsightly wires from the alarm system too. There is a big metal box full of wires on my kitchen wall that is for the alarm system and seems to be connected to the telephone lines. Could it be the alarm system causing the problem? What do I need to do to get all the jacks working? There is a dial tone to the house, but now the kitchen jack is the ONLY one in the house that works. THANK YOU!
