Why can’t I see presence information for all users?

Presence information is only available for users with a cloudUC Professional subscription. In other words, in order to view or have your presence information available or published, you must subscribe to a Professional level seat . For example if you have 4 users in your office and only 2 of them have Professional and the other 2 have Standard, the 2 Professional users would be able to see each other’s presence information where the 2 Standard users’ presence information would not be visible.
