Hello @VitoMattera ,
welcome to the Polycom Community.
Most likely, based on other posts here in the community, the units are defective. You may get them back for a while but this is a sign they are broken.
Not knowing the serial address of the device does not allow us to look them up and check how old they are.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
