Need some guidence. I installed a few 7965 phones that will not show the ring list , its will say ring list unavailable and it also doesn't show missed call history. I can install the phones in another building on campus and it works fine. It registers to the same subscriber as other working 7965's. Also it seems when I do a configuration change's on the new installed phone it seems to take a long time for the phones to reset. I have 6941 phones in the same locations that work perfect. Any Ideas ?
