Unity MWI status doesn't refresh

Unity 2.4.6.135 Call Manager 3.1.1 TSP 1.0.0.7

I am getting complaints of the MWI being on after messages have been cleared and being off when new messages are present.

I have discovered that the reason for this may be that the light doesn't change state when the phone is in use. Unity dials the phone to change it's MWI status 6 times. If the phone is in use for those attempts, the MWI doesn't change status.

Is there a fix for this? Can I increase the number of update attempts, increase the wait time between update attempts, or make Unity wait until the phone is on hook before it sends the MWI commands?

Re: Unity MWI status doesn't refresh

There is an option in Unity to refresh the MWI status on a periodic basis. The process is system wide, not for an individual phone. I usually set this to happen about 2am when system activity is light or non-existant. Unity will go out and send MWI on or MWI off based on what it thinks the status should be. This has been a successful workaround in a couple of installs I have worked on. The light should update even if the phone is in use, the only case I can think of where it may not behave that way is for a single line phone, i.e. 7910.
