Ease of use is enhanced on systems which allow the concept of a virtual endpoint. It should be possible to set up an endpoint titled say "Daily Production Meeting", that then auto answers with video on, anyone who starts a call with that endpoint. For regular meetings this is much better than an outlook entry, and can be joined with one click from any device with "Presence" display.
