IP phones that work with Skype for Business
You can choose from several models within the VVX line from Polycom, and phones running Lync Phone Edition (LPE).
Note: At this time, phones that are available in common areas such as lobbies aren't supported by Skype for Business.
We are working closely and partnered with Polycom to develop and validate the major update to the VVX series firmware that is supported for Skype for Business, which was released on October 1st, 2015. Polycom VVX models require version UCS 5.4.0A or higher firmware to be installed to support Skype for Business. New VVX phones will be shipped with this firmware pre-installed. To learn more, see Office 365/Skype for Business Online Solutions
Skype for Business works with the following Polycom phone models:
When ordering Polycom VVX phones, it is important to buy phones with a product ID that ends with -019. These are the version of each phone model that has the Skype for Business qualified version firmware version preinstalled. UCS 5.4.0A is the name of the release package.
Note: Newer desktop phone devices, outside of Lync Phone Edition, that are used to connect to Skype for Business Online will normalize to the certified firmware configured within the PSTN Calling Service. This will be the latest firmware certified by the vendor. The result could downgrade the device to a lower revision level - this is expected. If a more recent version is desired, you should work with your phone vendor to have more recent versions of their firmware certified.
