Hello,
About 2 weeks ago, I upgraded a client's Communication's system from 11.0 to 12.5. Ever since, Jabber has been doing a strange thing. On regular desk phones, the MWI light lights up okay, and notifies of a message on Unity, but Jabber doesn't get that same notification, even if it's the same number. signing out of Jabber, and signing back in makes the notification appear. But even after signing out and in again, it will show the previously unread voicemails, but not anything new. The users have to always log off and on again to get the notification on Jabber. If the user with the Jabber calls the voicemail, they can hear the voicemail, even if Jabber isn't notifying them of the message.
What could be causing this?
All Call Manager, Unity and Presence servers are on version 12.5
