Wondering what would cause a 6408+ set to go off hook by its self and or displaying garbage on the LCD. If it goes off hook I can just pick up the hand set and put it back down and things are fine, the same as with it displays garbage. Are these bas phones or bad wiring? Also I have had a phone take a over the phone page and hold the page ext. I have to go off hook and back on hook to release the page. Any one have any ideas about this?
