Introduction

This year, Microsoft will be making two (2) major changes to Teams Native phones:

So where does the chicken and the egg fit into this? Native Teams Phones must be running Android 12 to be managed in Intune with AOSP. Teams administrators need to get ready to update their phones to Android 12 before the switchover to AOSP in Intune. Later this year we will publish a follow-up article on configuring Intune and AOSP to support these updated phones, and as events warrant, we will publish updates as we get them from the Native Teams Phones manufacturers.

What Do You Need to Do As of Now?

AudioCodes

  • The C448s and C450s cannot be upgraded to Android 12. AudioCodes has provided a method for converting these phones to function through the Teams SIP Gateway. A One Voice Operations Center (OVOC) server is the only current way to convert these phones. We will provide updates on this when provided by AudioCodes.

HP | Poly

  • PVOS 9.0 should be available some time after May 17, 2024.
  • We will provide updates when available from HP | Poly.

Yealink

  • If you haven’t already done so, upgrade your MP54s, MP56s, and MP58s to a minimum firmware version of 122.15.0.142.
  • You should do this as soon as you can!

Management Platform Conversion from Android Device Administrator to AOSP

  • Stay tuned! As soon as we get the information and try it out, we’ll post our guidance.

Summary

There are some significant changes happening this year for Native Teams Phones—updating them to run under the Android 12 operating system and replacing the Android Management platform in Microsoft Intune. The availability of the updates and guidance from the manufacturers varies. Organizations should follow the guidance and upgrade their phones before Microsoft starts to deprecate the Android Device Administrator platform at the end of August 2024.
