Version 15.5 running supported firmware and stock 3cx template. The issue is that the power led blinks regardless of the setting under the phone provisioning tab. I have it set to voicemail only, and confirmed the ext does not have a waiting voicemail. The led indicator acts as expected until the phone goes into power saving mode. i.e. meaning when the display shuts off. Not the screensaver timeout or the backlight timeout, but the power saving settings. Anyone else experience this behavior?
