Hello @PauloFreitas ,
welcome to the Polycom Community.
Not knowing the history of this unit it is difficult to advice anything. The way you describe things the unit seems broken.
The only way forward, if the unit is still in warranty, is to open a ticket.
In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.
End Customers are unable to open a ticket directly with Polycom support.
If this is some sort of an Internet discounter providing your MAC address or your Polycom devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Polycom device from.
If the unit is no longer within warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
Polycom Global Services
