It is possible to configure the display of up to 4 external cameras already configured in the call panel, as it occurs with the MEETmonitor during a call.

Under Home settings (gear icon) > External cameras, select the camera number to enable the option.

This option will be available during the call.

During the call, press the panel icon. This will display a drop-down menu with the enabled cameras, and you can select the desired one so that the image shown in the call changes to the one coming from that camera.
