How to Firmware Upgrade a Yealink Phone from Skype for Business to Microsoft Teams

This week Yealink were the first phones to be certified and generally available for Microsoft Teams. The 3 certified Yealink phones, the T58A, T56A and CP960 can all actually run as Skype for Business phones or Microsoft Teams Phones.

Moving forward Microsoft will enable updating of Microsoft Teams phone firmware directly from Office 365, but if you want “swap” a Yealink phone from Skype for Business to Microsoft Teams, here are the steps.

If you prefer a nice video of the Yealink Microsoft Teams firmware upgrade process, my friend Josh Blalock has one here.

In this case, I was flashing a T58A, but the steps are the same for all devices.

1) Login to the Yealink phone web admin console via a Browser

Yealink phones have a web admin console. You can find the phones IP on the phones settings menu

Navigate to that IP in a browser

The default username password is admin / admin.

2) Download the Yealink Microsoft Teams Firmware and Upload it to your Phone

You can download it directly from the Yealink site, you don’t even need a login

Ensure you have the right firmware for your device, navigate here and upload the firmware

3) Licence Upload – Not required if moving from Skype for Business

Note, if you are moving from Skype for Business, you should not need a licence. I was moving from a Teams beta firmware (which didn’t need a licence) so I needed to upload a feature licence. If you need a licence Yealink will have a portal, but for now, it’s a manual request process. If you need it best to contact your Yealink device provider.

This is the web view after the Teams firmware update

4) The phone will boot into Microsoft Teams setup process

Language selection


Multi-Factor Prompt

It’s a bit strange it talks about audio, video and screen sharing on an audio-only device

Choose if this is a shared device (like a meeting room) or a Personal device

  • Hi Tom, thanks for your blog. we are just playing with this now. I have noticed that voicemails don’t appear in the Voicemail tab on the phone. Do you have a similar issue? They do appear OK in the Teams client for Windows and iOS.

  • Hi Tom

    we were just looking at trying to get a Yealink W52P to work with S4B

    By the looks of things it looks like we will need a S4B version of the firmware

    we are not looking for full S4B functionality just for the W52P to work as a voice device

    is there anything in the future that will allow cordless S4B devices

    not wanting to use a mobile and the app



    • Hi Richard,

      I haven’t seen any plans for a cordless Teams phone yet. You could run a standard Dect or Wi-Fi Phone via a SBC, but I appreciate that’s not quite the same thing.
