Important Note About Use of UC Software in Skype for Business Deployments


Customers in Skype for Business deployments should only use software releases that Microsoft has
qualified or maintenance releases built on a qualified release.


Microsoft qualification may fall behind Polycom Generally Available dates for UC Software, hence we request customers to check whether a release has been qualified before deploying new software. For all latest Microsoft qualified releases, visit the Polycom UC Software for Skype for Business Deployments page for a list of qualified releases.


New Features and Enhancements

 

Polycom UC Software 5.9.4 includes the following new feature and enhancements:

  • Third-Party Application ID Implementation on Skype for Business Phones
  • Sign In Remotely Using Web Sign-In for Skype for Business

Third-Party Application ID Implementation on Skype for Business Phones


Microsoft announced the end of support for the existing Azure application ID currently used by third-party device vendors that use the OAuth 2.0 authorization protocol.

 

To retain authentication to Microsoft services and the ability to sign in to Skype for Business, you must update the firmware to implement a third-party application ID on all impacted certified Skype for Business phones by January 15, 2020.


The following deployments include Skype for Business IP phones certified under Microsoft’s 3rd Party IP Phones (3PIP):

  • Skype for Business Online
  • Skype for Business On-Premises Hybrid (with modern authentication deployed)

Polycom adheres to the Microsoft announcement and has implemented the third-party application ID.


To implement the third-party application on Skype for Business phones:

  1. Go to the consent URL and sign in with tenant administrator credentials.
  2. Click Accept to grant permission to allow the Poly ID application to access the required resource's permissions.

    Note: You must go to the consent URL and accept permission before you upgrade to the new
    firmware.
  3. Upgrade the impacted phones to the new firmware version

This section provides information on constraints and limitations when you install UCS 5.9.4 in your
environment.

 

  • Authentication of Microsoft Exchange 2013 Services

Authentication of Microsoft Exchange 2013 Services

 

Polycom UC Software 5.9.4 contains embedded Poly application ID code, which can cause the
authentication for Exchange services with Hybrid Modern Authentication (HMA) enabled to fail with OAuth 2.0 on VVX phones.


Downgrade Behavior from Polycom UC Software 5.9.4

 

Downgrading from UC Software 5.9.4 to any earlier UC Software version may result in sign-in failure. To continue using Skype for Business on VVX phone successfully, re-sign into Skype for Business.
