4.0.8.0 update started pushing out to some SRS v2 devices via the Store on Friday, July 6th. We expect that the update will be made available to all SRS v2 devices in the coming week.
4.0.8.0 enables both Skype for Business *and* Teams meetings support on Rooms Systems devices. Teams is turned off by default once the update is applied. Admins can enable Teams locally in device settings or via a remote xml push.
