Microsoft Teams Casting and Companion Mode

Do you take your laptop or mobile into a meeting in a Teams Meeting Room? If you do this blog is for you.

Casting

If you have you device with you and simply want to share something, there is no longer any need to connect your laptop to the meeting room system. The cast feature uses bluetooth to locate the meeting room, so both the companion device and meeting room need bluetooth enabled for this to work. First choose Cast from the … menu

Then wait for your device to locate the meeting room and select the room and click Next

Your device will automatically join the meeting in ‘companion’ mode, with the camera, speaker and microphone off, and share the content.

Companion Mode

Companion mode (not its official name) is where you join a meeting but select the meeting room as the audio device. Note this is different to joining the meeting as yourself from a second device, here we are joining as ourselves but with audio disabled. For more information on joining as yourself from two or more devices see the guide for joining a Teams meeting on a second device from the Desktop or Mobile.

To join using room audio from a mobile device, open the meeting from your calendar and select Join. The Teams meeting should detect the room audio if the meeting is already in progress and default to that option.
