I've noticed that two Polycom Group series devices that have the Lync Interop licence installed provide good quality (1080p) video calls when making a point to point lync call but if the same two devices connect by joining a Lync conference, by joining via a calendar appointment for example, the resolution drops to 640x368
I documented my findings in a quick blog

anyone been successful getting the devices to connect at a better resolution?
