Yealink SIP-T58A Web User Interface Access/Connectivity Troubleshooting


Our support guides for the Yealink SIP-T58A show you how to access features directly from the phone's user interface. But for more advanced features (such as DND or forwarding authorized numbers) or ease of access, you can also customize your phone via a web user interface.


IP Address and Login Credentials


To access the web user interface you need to know two things:


  1. The IP address of the phone.

    To obtain the IP address, swipe down from the top of the screen to access the Quick Settings menu or swipe left or right to show the second idle screen. Tap Settings  ( ) and Status. The IP address will show at the top of the General block.

    If your local network is using a DHCP server, the IP address is configured automatically when your phone is initially powered on. If the phone cannot obtain the IP address automatically you may need to configure the network settings manually.

  2. The phone's current administrator or user login credentials.

    The default administrator credentials are “admin" (case-sensitive) for both the user name and password. 

    The default user credentials are “user" (case-sensitive) for both the user name and password.

    When we initially provision your phone we usually change these passwords. If the default passwords are not accepted and you are an existing client please contact us for assistance.

Web User Interface Access


To access the web user interface do one of the following:


  • Enter the IP address in a web browser on a computer or a mobile device that is on the same network as the phone.

  • When prompted by the login page, enter the current administrator credentials in the username and password fields and click Confirm.

    If the administrator password is not accepted, you can try entering the user credentials in both fields. This will provide you with a more limited access to some features.

  • If enabled on your phone and supported by your browser, you can skip the login page by entering a URL request in your browser.

    To do so you use the format “https://username:password@phoneIPAddress” (for example, https://admin:admin@192.168.0.10).

    If all details are entered correctly your browser will open on the Status page.

For security, after accessing the web user interface you can change the admin password from Security>Password. You can also change it from the phone user interface by navigating to Settings>Advanced Settings>Set Password.


Connectivity Troubleshooting


Your computer or mobile device has to be on the same network as the phone. This means a remote connection is not possible. 


If you are unable to connect, even when in the same office or location as the phone, try one of the following:


  • Swipe down from the top of the screen to access the Quick Settings menu or swipe left or right to show the second idle screen. Tap Settings  ( ) and navigate to Advanced Setting (enter the administrator credentials if prompted to)>Network>Web Server.

    Make sure that HTTP/HTTPS is Enabled.

  • If the phone is using a Wi-Fi network without a physical network connection make sure that Wi-Fi is enabled and connected properly. See more information here

  • Try rebooting the phone and your main router.

  • Try using your browser in a private or incognito mode or try using a different web browser.

  • If you are using a browser with an ad-blocking feature or if the browser has an ad-blocking extension/add-on, the Advanced Account or Network settings may not be accessible. To fix this disable the blocking for the web page of the Web User Interface.

    Disabling or blocking web scripts on your browser (commonly JavaScript) may also create problems. Either enable the script option for the Web User Interface or use another browser.

  • If none of the above help, you can try to connect a network cable directly between the phone's PC port and a computer or plug the phone directly into your router.
