OAuth 2.0 and third-party application ID: Timeline extended to July 15th, 2020!

All certified Skype for Business IP phones must be updated by July 15th, 2020 (originally January 15th, 2020). Without the update, successful authentication to Microsoft services on IP Phones will fail. Specifically, signing to the device via web or using a user name/password on the phone will fail.

By Suzanne Whetton

As a result of Microsoft's change, Skype for Business IP Phone partners have made a code change to embed the partner specific application ID in their firmware. The customer tenant admin will be required to confirm consent to allow the third-party phone application to be granted the necessary permissions (the same permissions currently being used by Skype for Business IP Phones).

Customer admin will need to perform a one time, tenant wide (all users), consent per IP Phone partner.

This change requires customers to perform a 2 step process:

  • Step 1: Accept permissions request using the consent URL (can be done at any time)
  • Step 2: Upgrade all impacted phones to the firmware version communicated by the Microsoft IP Phone partners

VIA Skype for Business customers are encouraged to make these changes before the update deadline.
