Hello @FabioBip,
welcome to the Polycom Community.
As already outline by my colleague this most likely needs to get into support.
The community's VoIP FAQ contains this post here:
Jan 28, 2013 Question: Time and Date flashing or unable to set time correctly
Resolution: Please check => here <=
Mar 15, 2016 Question:Why does a Polycom phone show the wrong Daylight Saving Time?
Resolution: Please check this post => here <=
In addition the Skype FAQ contains:
Jan 17, 2017 Question:How can I troubleshoot simple Skype for Business, LYNC or Office365 issues?
Resolution: Have a look => here <=
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 please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you. This may not be who you purchased the Polycom device from.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
