Norstar Compact ICS REL 5 NT7B56FA-93
has 6 active lines and 16 ext only (2 used for Call pilot 100) could not activate another phone set
check the wall jack, the cabling, the signal on each Pair
i moved an active set to this wall jack just for a test, it worked fine
the system would not allow more than 16 active set?
Thanks Gens
