There is no local camera, can I preview the remote site?

Yes, the current call policy is as follows:

There is no microphone device (or the microphone does not have permission), and calls and responses cannot be made.

Reason: When there is no audio, the basic voice is not available.
During a video call, there is no need for a camera device (or the camera does not have permission).

Impact: A user without a camera (or without permission to the camera) does not push the video stream, so other users cannot see the user. However, this user can preview the user who pushed the video stream normally.
