Cymbus allows you to share your online status (presence) with team members (Buddies). Your status is displayed on the Messaging tab.
When Cymbus is launched, your online status is Available. To change it, tap next your status and select a new one: Away, Busy, Do not disturb, Appear offline. Optionally, type in a custom note to be displayed next to your status.
Cymbus updates your status to On the phone when you make or receive a call and your status was Available.
