Line 3 is already in trk grp 1 and co setting is high to low. i have even tried putting just line 3 in TG1 but still when i dial 9, display on phones still shows line 2.
I have a Preprogrammed NCP500 from someone. It had 2 CO programmed in Trk grp 1. When i am programming 3rd single line and trying to access the group (dialing 9), i am always getting line2. Is something forcing the system to grab line 2 only?
