When a user sets their presence status to 'Do Not Disturb' in the desktop app, it appears as 'Busy' on the desktop app. When they set their desk phone to 'DND', it doesn't change their status in the desktop app.
Prior to the software change this year, the Polycom VVX410 system in the office was able to be used to show status. For example, pushing the DND soft key on one's phone, would display on others phone with a red bar. Currently, a red bar only shows up if they are on the phone, but the way it functioned before allowed us to know they were busy (not at their desk or on their cell phone). I really liked this functionality, please make this available again.
