Hello @igibason ,


Welcome back to the Poly Community.

Our partner Microsoft usually only certifies and test major releases. We as the Manufacturer produce Maintenance releases.


All your phones can use UC Software 5.9.6 and are supported by Poly in a Microsoft environment.


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
