I know this should be simple ,, but i haven't done but few in 10 yrs,, the system is mostly at default settings for the all group settings ,, when i change the line 1,2& 3 not to ringing , and press hold it comes back with error 3 in the display ,, do i have to take those extensions out of the Group Call Pickup or Station Hunting group. ?? There is no Voicemail and it is Analog Trunks.
