If you and the other user in a live call are both using the desktop or mobile app, any of you can also share your screen with the other person. To start a one-on-one call to screen share in the app, during a live call, tap the Video button and then tap Share screen from the dropdown menu.
Please note that for iOS, a screen share confirmation will open up. Select Vodafone with RingCentral and then tap Start broadcast to begin sharing your screen.
You will be switched from the active call to an active video meeting and the active call window will be closed. The voice is carried over to the meeting and the voice in the active call will be dropped. You can then start sharing your screen with the other user. If you close the share window screen, the call will return to an active video meeting screen.
