Friends My ip phone reboots automatically and frequently. what is the issue. pls let me know
You could try checking your switch port for interface resets
Please check which FW are you running, from the device status menu. You might need to upgrade it.
I would say you have a flakey POE port or POE problem.
Try plugging in a power brick to the phone to see if it resolves the issue. Then back-track.
Another simple fix would be to switch ports where the phone is plugged into.
I have seen blades in 4xxx go on the fritz with POE problems.
