I am trying to log in to Skype for Business on my Polycom VVX 411 phone and it fails every time. I have tried "user credentials", "web sign-in", rebooting the phone, and using the web configurator but nothing has worked.
I am using
UC Software Version 5.6.0.17325
and
Updater Version 5.8.0.19248
The logs are attached.
Solved! Go to Solution.

Hello @mhurley,
Yet after all this you did not think to attach the logs so other members can verify your changes ?
Please go ahead and escalate this into Polycom support.
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.

Following the FAQ you directed me to I uploaded configuration files to change the time, changed the SNTP server in both the phone and the web configurator, disabled the DHCP, and set a new DNS server. Nothing has worked to set the correct time and date on the phone, and it still does not sign in and find service.
