Yealink SIP-T58A Rebooting, Updating Firmware/Configuration, Factory Reset

If your phone malfunctions or requires 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 configuration - settings or configuration changes made by Telebroad or your system administrator are applied to the phone when you trigger a configuration update. Depending on the update method this may not require you to restart your phone.


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 may do this if you forgot your phone's admin password


Rebooting


Rebooting your phone is usually a safe and easy method to resolve functionality issues. However, you may want to consult your phone system administrator first to make sure the issues are not related to network problems or other external causes. 


To reboot the phone via phone user interface:


  • Do one of the following:

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

      Select Settings and navigate to  Basic Settings > Reboot.

      Select Reboot.

    • Long press the * key on the keypad when the phone is idle.

    • Access the phone via the web user interface as explained here.

      Click on Settings > Upgrade.

      Click Reboot.

  • Press or select OK when prompted to confirm that you want to reboot the phone.

Updating Configuration


Changes in the system or network of your office may cause problems with the functionality of your phone. To restore compatibility or simply to apply new settings for improved workflow, your system administrator may ask you to update the phone's configuration after he has prepared the relevant configuration file. 


When you trigger the configuration update the new configuration file is downloaded from a provisioning server to the phone's flash memory and the update process is completed automatically. 


To update the configuration of your phone:


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

  • Select Settings and navigate to Basic Settings  > Update Configuration.

  • A "Provision now" message will prompt you to approve the update.

  • Select  .

Upgrading the Firmware


The latest firmware file can be downloaded from the Yealink support portal. The downloaded file should be stored on a computer or network location that can be accessed by the web interface. 


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.


To check the firmware version via phone user interface: 


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

  • Select Settings and navigate to General.

  • The firmware version shows under the Status tab (the first choice.)

To view the phone status via web user interface:


  • Access the web user interface as explained here.

  • The firmware version is the first item found under the Status > Status path on the first page of the web user interface.

  • Click OK to confirm upgrading.

  • The phone will display a "Firmware Update" message. The process will complete successfully after startup.

Factory Reset


This is only recommended after you have tried all other troubleshooting suggestions since the operation will delete all your personal configuration settings and reset them to the factory defaults. It is therefore advisable to have your phone system administrator backup your personalized settings before proceeding with a factory reset.


To  perform factory reset of the phone via the phone user interface:


  • Do one of the following:

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

      Select Settings and navigate to Advanced Settings.

      If prompted for a password enter the default password (admin) or the current admin password of the phone.

      Select Reset Config.

    • If enabled by your phone system administrator, you can long press   (redial) on the keypad when the phone is idle.

      If prompted for a password enter the default password (admin) or the current admin password of the phone.


  • The phone prompts you to reset the setting or not.

  •  Select OK  to confirm.

  • The screen prompts “Welcome Initializing…Please wait”.

    The phone will be reset to factory successfully after startup.

    The process may take a few minutes. Do not power off until the phone starts up successfully.

If you forgot or don't know the admin password of the phone you can contact your phone system administrator and ask him to change the phone's settings so it does not require one when you long press the redial key (the specific configuration file setting is “features.factory_pwd_enable=0” ). Update your phone's configuration if your administrator asks you to. You should now be able to reset your phone without being prompted for a password. After the reset, the default password (admin) should work. 


To perform factory reset of the phone via the web user interface:


  • Access the web user interface as explained here.

  • Click Settings > Upgrade.

  • Click Reset to Factory Settings in the Reset to Factory field.

  • The web user interface prompts “Do you want to reset to factory?”.

  • Click OK to confirm.

  • The screen prompts “Welcome Initializing…Please wait”.

    The phone will be reset to factory successfully after startup.

    The process may take a few minutes. Do not power off until the phone starts up successfully.
