Once a Rapid Connect QR code has been generated on a mobile device, headset users who are already in a call can summon the mobile device into their meeting.
In a call on headset, say "more" and say "add device".
A camera screen will open. Position the Rapid Connect QR code displayed on the mobile device you'd like to summon in the center of the camera feed. Once the code is scanned, you will be returned to the meeting, and the Rapid Connect device will be pulled into the meeting.
