That’s a Cisco Meraki device. It’s Enterprise grade equipment. Part of the appeal of that line of device is being able to basically just register the serial number of the device on a dashboard and the configuration that you pre-configured on the Dashboard can be automatically pushed to the device when it is powered on. In theory, it means you can basically ship it to a dinosaur of a user and ask them to plug it in and turn it on. In practice? Stuff like this happens all the time if you try to do that.

I think that might be a licensing issue. The call out feature is not included in the base Teams licence. You’ll need an audio conferencing for Teams licence (included in E5) on the account of the guy who created the meeting to have the call out feature enabled.
