Firmware Upgrade
There are three methods of firmware upgrade:
• Manually, from the local system for a single phone via web user interface.
• Automatically, from the provisioning server for a mass of phones.
• Upgrade all device software to the latest version with one click on the Microsoft Teams & Skype for Business
Admin Center. It is only applicable to IP Phones running the Teams firmware.
Note: We recommend that phones running the latest firmware should not be downgraded to an earlier
firmware version. The new firmware is compatible with old configuration parameters, but not vice versa.
Note: For T58A/T56A Teams phones, if you upgrade the firmware from 58.15.0.20 to 58.15.0.41, you need
to upgrade to 58.15.0.26 first and then upgrade the firmware to 58.15.0.41.
