I’m not sure how long it’s been there for, but there is a user guide on Meridian’s product page – which I haven’t seen before - but it may have been there a while!

It mentions that certain devices (e.g. 210) won’t power it over SpeakerLink.

User Guide

It also goes through the many configuration options should the out of box functionality not be appropriate.
