Updated - Microsoft Teams Phone System with Yealink DECT

Yealink IP DECT with Teams SIP Gateway

Support for Yealink DECT Base station and handset combinations have recently been released for support with SIP Gateway allowing for multiple handsets behind a single base-station to integrate with your Teams Phone solution. This is a great, low-cost, device solution for small branch offices, or plants who depend on DECT wireless performance, and those who need hard-button devices for user who often wear gloves.

Models Supported – W70B/W80B/W80DM/W90B/W90DM and associated handsets supported with these base-station models


Background

Microsoft and OEM device manufacturers are expanding the list of supported devices through Teams SIP Gateway. If you are not familiar with SIP Gateway, take a look here - Plan SIP Gateway - Microsoft Teams | Microsoft Learn

This link also includes a growing list of supported device models.

(Note – device certification is provided by the OEM manufacturers who offer their devices to integrate with Microsoft Teams. Microsoft does not provide any OEM firmware directly)

You will want to ensure you follow the guidance here for enabling SIP GW in your tenant and within your network security rules - Configure SIP Gateway - Microsoft Teams | Microsoft Learn



Preparation

The key to this implementation is recently updated firmware made available from Yealink – HERE

Ill speak more to the process and why this firmware is critical, but wanted to call out the link, and the area under Yealink Support if you need the navigation steps –

 Support Home-> Microsoft/ZOOM/RingCentral/BlueJeans Devices -> Teams PhonesSIP -> Gateway DECT

Teams integration for these devices is rather simple, the purpose for this update is to clarify steps, since there are some notable differences in how these devices connect to Teams, from other analog or legacy SIP devices.

First you will want to identify the geographic location you plan to deploy. This is key, since there is a specific firmware revision defined for each of the 3 SIP Gateway clusters provided by Microsoft (note image below). Within each download ZIP file – you will find the needed firmware for the W70/W80/W90 base-station models from Yealink. Handset upgrades are provided in a different ZIP file, noted in blue below. Take note of your handset model and select the correct file.

The following guidance assumes you are familiar with accessing the Yealink management interface through a browser. More information is available in the device support docs if needed. I am using a W70B station with W73H handsets for this guide.



Step 1 - Often recommended, start by factory defaulting your device prior to upgrade. I cant confirm this is a requirement, but its always good to start clean. Take note, if your Yealink’s have been previously deployed using other methods (connected to PBX, or direct to SBC) the factory default may clear locally stored dialing rules, speed-dial contacts, or phone book configurations.





Step 2 – proceed to update the base station using the defined firmware for the region you plan to deploy (either Americas, EMEA or APAC).  You may also want to update the handset after the base.



Once your device is updated, this is where the process differs from other SIP Gateway devices. You will not need to “provision” the MAC address in the Teams Admin Center as you would a native Teams Phone or other SIP Gateway phone. Checking the Configuration Setting Page from your Yealink Phone – you will see something that looks like below:



After reboot, you will notice the Account -> Register settings are already filled in. This is done as part of the firmware upgrade process. You will not need to adjust any settings in the account or line configuration settings.

The Handset will now look like this:

     


               

Step 3 - Note the Sign-In option from the left side action button. Follow the remote device login instructions from a web browser – logging in the desired user or shared device account using the pair code and account credentials assigned.

 (NOTE – you will not see “Device Waiting for Login” in Teams Admin Center – as you might with other activations)

Proceed to https://aka.ms/siplogin

 



The handset is now signed in (in my case using a shared device license and account)




     

Boom – you are done !!

Update - July 2024

Recently needed to migrate this device to a new tenant and figured I would share steps to move this Yealink DECT to a new tenant environment.


Step 1 - Reset to Factory Defaults


Step 2 - Downgrade the Device Firmware to factory base firmware (non-Teams Sip Gateway version) - HERE

Step 3 - Upgrade to Teams SIP Gateway version, which will reset the provisioning server and pairing status - HERE


From here you can proceed to SIP Device Login

Enter the shared device account credentials in the browser.

Proceed to the DECT Handset, and select Sign In (left action button below the screen). A Pair Code will be generated used in the remote login page on your browser:



and back in action !!
