We are using Unity 4.1 unified messaging. I do recieve my voicemails via email or can listen to them on my phone. But MWI is not working. When I try to resynchronise manuly in get an error telling me to check if all unity services are running. I found the AvNotifierMgr is not running. I tried starting it manually without success. I rebooted the Unity server. Still the services is not running.
