We are encountering a problem with some users on our CCM 4.X/Unity 4.2 Cluster. The IP phone shows "You have voicemail" , the MWI Lamp stay ON, but in reality when user check the VM ,there are not voice mail messages . After troubleshooting the Unity looks that is Fine, and problem appear to be in CCM.
Has someone encounter this issue and what was the fix?
Many thanks in advance,
