Have a customer that we installed a MICS (R7.1) w/ a CallPilot a couple of years ago. Everything is working great until they had some kind of power outage late last week. Out of the 25 sets they have, about 8 of them are having display issues with the screens next to the feature keys on the phone. Main display works properly, but the indicator lamp that appears next to each feature key (such as when a line is in use, another extension in use, etc.) do not light up. The keys on the phone do work though.
Unplugged the phone and plugged back in. All lights flash as if it is coming up normally, but did not fix the issue.
Swapped with a known working phone, and the issue persists. If I take the problem phone to a known working station port, it works perfectly fine.
Power cycled the system, and no change.
As far as I can tell, all programming is in tact and everything is working, outside of the display problems.
Any suggestions?
