What is presence?
In the new user control panel, you will see a menu at the bottom of the page that shows your presence state as seen in the image above.
Presence allows you to control how the PBX interacts with you as a user.
Presence gives the system and other users in your organization a generalized status so they may respond accordingly.
Is this just a UCP thing?
