As the Subject says, this phone has buttons that aren't responding, I tried Firmware upgrade, downgrade and Global Settings/Factory Settings: Restore.
Some other buttons also seem affected, such as volume-DOWN.
Is there anything else I can try?
welcome to the Polycom Community.
What is the history of the device and what environment is it being used?
A software should not change the functionality of a keypad but have you tried factory restoring it to exclude any changes via provisioning?
