How to do a Firmware Upgrade (Yealink)

Before upgrading to the latest firmware, you should read the related firmware notes and possibly consult with Yealink's support to ensure there are no compatibility issues or other potential conflicts. If such issues or conflicts do happen after an upgrade, you may need to downgrade to a previous firmware version or perform a factory reset

1. Go to Yealink’s resource center and search for the model you are looking for: You may simply type the model to search for, especially for older phones

Search the model

Choose Firmware then click Inquire

Click the Latest ROM file and download it

2. Go to the support site of Yealink and look for the model

• Select the series you are interested in e.g T4 for T46U

• Click on the phone you are going to upgrade
• Click Firmware
• Download the latest Rom File

Checking the Current Firmware Version

You can check the current firmware installed on the base or a handset to see if an update is indeed required.

To check the base station firmware via the handset:

• Press the OK 3 to enter the main menu.

You may need to provide some of this information, besides the firmware version, to your phone system administrator for additional phone support or maintenance.
