Yealink continuously provide firmware releases to further improve features and fix bugs, but how do you go about upgrading the firmware on your Yealink IP phones?

After downloading the latest firmware from Yealink’s website you can either manually update from the local system for single phones or mass-provision automatically for multiple phones. The following table lists the associated and latest firmware names for each Yealink IP phone model (X is replaced by the actual firmware version).

Method 1:  To manually upgrade firmware via web user interface for single phone:

  1. First, save the firmware to local system
  2. Click on Settings -> Upgrade (For T3x and VP530, click on Phone -> Upgrade)
  3. Click Browse
  4. Select the firmware from the local system
  5. Click Upgrade – A dialog box pops up to prompt “firmware of the SIP phone will be updated. It will take 5 minutes to complete.  Please don’t power off!”
  6. Click OK to confirm the upgrade

Note:  Do not unplug the network and power cables during the IP phone firmware upgrading process.  Also do not close/refresh the browser when the IP phone is upgrading firmware via web user interface.

Method 2:  To mass provision via provisioning server:

IP phones support the use of FTP, TFTP, HTTP, and HTTPS protocols to download configuration files and firmware from provisioning server, and then upgrade firmware automatically.  You can configure the way your IP phones download firmware stored on provisioning server in one of two ways:

  1. Check for both configuration files and firmware stored on the provisioning server during boot up
  2. Automatically check for configuration files and firmware at a fixed interval or specific time

Configuration changes can be performed using the configuration files or locally:

  • Configuration File ( <y0000000000xx>.cfg ) – Configure the way for IP phone to check for configuration files.  Specify the access URL of the firmware. Refer to Upgrading Firmware on admin guide for more details.
  • Local (Web User Interface) – Configure the way for IP phone to check for configuration files.

For Yealink T19P, T2 series, T4 series:

In <y0000000000xx>.cfg, you can configure firmware url as below.
———————————————-
#!version:1.0.0.1

  6. (If the [/b]Weekly On[/b] radio box is marked) Enter the desired time in the Time field.
  7. (If the Weekly On radio box is marked) Check the desired checkbox in the Day of week field.
  8. Click Confirm to accept the change.
  9. Note: When the “Check New Config” is set to “on”, the IP phone will check for both firmware and configuration files stored on the provisioning server during boot up.  Refer to admin guide for more details.

For Yealink W52P base station:

You can upgrade your base station to the latest firmware version. The latest firmware version not only improves the performance of the base station, but also provides more features compared to the previous version. This section provides you with instruction on upgrading the base station via web user interface (Refer to Yealink W52P IP DECT Phones Auto Provisioning Guide for information on upgrading via auto provisioning).

To upgrade base station firmware via web user interface:

  1. Contact your system admin for the latest firmware file and store it on your local system in advance
  2. Click on Phone->Upgrade
  3. In the Select and Upgrade Base Firmware field, click Browse to locate the firmware file from your local system.
  4. Click Upgrade to upgrade the firmware of the base station.
  5. The browser pops up the dialog box “Firmware of the SIP Phone will be updated. It will take 5 minutes to complete. Please don’t power off!”.
  6. Click OK to confirm upgrading.  The upgrading process will take a few minutes. The power indicator LED on the base station flashes when the base station is during the firmware upgrading process.
  7. Note:  Do not refresh or close the browser during upgrading process of base station

Once the base station firmware has been successfully upgraded, the base station reboots automatically. The handset will perform an auto registration to the base station. You can check the firmware version of the base station using the handset. For more information, refer to Yealink_W52P_User_Guide_V40_1

For Yealink W52x handset:

You can upgrade W52x handset firmware via a USB tool or over the air (OTA). Upgrading handset firmware via the USB tool (developed by Yealink), you need to purchase a USB cable in advance, and then upgrade the handset firmware one by one.

Upgrading handset firmware via OTA means that the handset firmware can be upgraded through a wireless DECT connection (L2CAP). So a USB cable does not have to be plugged to the handset for firmware upgrade. OTA enables the distribution of new firmware to the subscribed handsets.

OTA upgrade capability is restricted to specific firmware versions and handset hardware:
* Handset with firmware 26.40.0.15 or later
* Base station with firmware 25.40.0.15 or later
* Handset with hardware 26.0.0.6 or later

Please note that OTA is only available when meeting the above three conditions simultaneously.  Upgrading handset firmware may take a period of time, so you may wish to upgrade the handset outside of work hours to avoid affecting the normal use.  Please refer to Yealink’s guide on upgrading W52x Handset firmware for more details.
