Using desk phone companion mode

Companion mode integrates Zoom meetings with your provisioned desk phone. With companion mode, you can do the following:

• Join a scheduled Zoom meeting and use your desk phone as the audio device.
  For example: You can join a meeting after seeing a calendar notification. After joining the meeting using the Zoom desktop client, you can press the Zoom meeting key on your desk phone to join audio using your desk phone.
• Receive a meeting invite and join the meeting using your desk phone as the audio device.
  For example: A colleague using the Zoom desktop client invites you to an instant meeting. You will see an incoming call on your desk phone and accept it to join audio using your desk phone. You can also accept the meeting invite on the desktop client to enable video and screen sharing.

Requirements for using desk phone companion mode

• Provisioned desk phone that supports companion mode
• End-to-end (E2EE) encryption for meetings disabled
