Environment: CCM Cluster v4.1 with unity 4.0.
When a user receives a voicemail the message waiting lamp does not show this to the user. On the (line of the) IP phone the Message Waiting Lamp Policy is configured as 'Use system policy' and under Service Parameters is the Message Waiting Lamp Policy set on 'Primary Line - Light and Prompt'. I've already restarted Unity and all voicemail ports are up 'n running. By dialing the unity extension the system says there are new messages for the user so whats going wrong?
