I have the above system with 7 lines coming in and 16 stations. Today the display set is the only one that rings and when answering an outside call at one of the other stations, you have to press the flashing line instead of just picking it up and answering the call. What happened? I expect someone has entered a code or something to change the system. I have the user guides but I cannot figure out what happened.
Thanks in advance,
Bill.
