Yealink SIP-T58A Rebooting, Updating Firmware, Factory Reset

If your phone is malfunctioning or require updates you or your phone system administrator may want to perform one of the following:


Rebooting - this will bring the phone back to the its last configured state. It is also required sometimes when TeleConsole settings have been updated such as after modifying TeleConsole BLF settings.


Updating firmware - firmware is the software that loads when the phone is started and controls its functionality. Updating it to a newer version when one is released may resolve or improve phone performance issues. 


Factory reset - this erases the current configuration and apply the original configuration the phone was shipped with from the factory.

You can check the current firmware version installed on the phone to see if an update is indeed required.


When checking the firmware version you will see additional information including IPv4 or IPv6 status, network configuration, and account status. You may need to provide some of these details to your phone system administrator for additional phone support or maintenance.

  • Swipe left or right to go to the second idle screen or swipe down from the top to show the control center.
