Using End-to-End Encryption (E2EE) during a Zoom Phone call

If your account owner or admin enabled End-to-End Encryption (E2EE) for your account, this feature will help add an extra layer of privacy to your phone calls occurring over Zoom. You will be able to quickly switch your calls to be encrypted when necessary, and if your calls are automatically recorded, you will see an option to stop the recording to make the switch if you are allowed to stop your recording.
