I have an MWI problem. Everything looks normal except the light on the phone doesn't lit and no envelop in the screen. I can leave voicemail and I can hear new voice message. I check the Users ->Users -> BR1 Ph1 -> Edit -> Message Waiting Indicators -> current status is also ON. One thing I don't understand here is when I go into that MWI and click save then the Current status change to OFF. But if I go up one page and click "reset all" then the current status change back to ON. I call the MWI number then the phone disconnected immediatelly. I also restarted the Unity Conn to.
I tried to troubleshoot using this link. There are 15 places to check and I've checked most of them except some I don't quite understand. Should I try the 15 to Diagnostic Traces? That looks very complicate. This happens to all phones. I used Unity Connection 8 and CUCM8.
I attach some screenshot from CUCM and UC. Thank you!
