I have one phone 7940 that the MWI will not light. I look at status is Unity and the status updates properly but the phone light will not light. The MWI turns off and on fine if I dial the ext to light and unlight. Any ideas.
In your CCM service parameters do you have Multi Tenant MWI enabled or disable on each of you CCM's?
If you do not have that enabled then you can use translation patterns to route MWI from a partitioned Unity port.
Do your Unity ports have a conflicting pattern available to their CSS with that of the MWI on/off codes? or that device's extension? To lamp the lights Unity dials the MWI on code and THEN appends the EXT so if the port can't reach the device then you are out of luck with MWI.
Can you transfer from Unity to the device reliably?
I am having a very similar issue with one 7960 only the MWI light won't turn off. The status changes in Unity correctly but the phone's MWI status doesn't change. I can turn on and off the MWIs on other phones in the same location, PT, CSS, etc. Any ideas?
