I have an intermitent ringer fault with 2 2010 dt handsets. When dialled they sometimes ring, they sometimes don't. The problem seems to be rectified when u unplug the phone and plug it back in. However this is only a temporary fix, as they soon stop ringing again. The phones are plugged into a 403 which has been replaced and also upgraded. Obviously the phones have been swapped out, nothing seems to clear the problem, anyone help?
