On one install, we have a UC320W with a dozen phones, mostly SPA504's but a few SPA525s too.
We also have 3 SPA500S sidecars on the SPA525s.
Every once in a while, all 32 buttons on a sidecar will light up orange, and remain lit for a period of time (a couple minutes to 10 minutes).
The buttons seem to work from what the client tells us, but they are showing orange.
The phones that correspond to those extensions also appear to be working during this time.
One one phone/sidecar that this is happening on, it is connected to the UC320W wirelessly (and the UC320W is only about 10 ft from the phone).
Anyone seen this issue before?
Firmware is 2.1.1
