This idea has been merged into another idea. To comment or vote on this idea, please visit ENTCOM-I-120 RingCentral App needs a setting to "Bring to front" on an incoming call, not just a task bar notification.
"Keep app in foreground" setting within the RingCentral Phone app is extremely useful, but this option does not exist in the RingCentral App. This is a great feature to have when working in a Remote Desktop environment. This avoids having to minimize RDP every time a call is placed through the RingCentral App.
