DND on all Deskphones

I would like to see a feature on all Ring Central Deskphones, to integrate their DND status with all other agents/ representatives in the company. We can see when they are on a call, or placed a call on hold, but cannot see if they are on DND. This would alleviate a lot of headaches for our team, if they could see if someone is available or not... This is a cloud based system. It needs to be able to integrate with all deskphones.
