For a complete, enriched Teams experience, we recommend customers use certified IP phones running Microsoft Teams natively and available on Teams Marketplace.
If customers have IP phones certified for Skype for Business, and are preparing for an upgrade to Microsoft Teams, the Skype for Business phones will continue to sign into the Skype for Business service and support a limited number of core functionalities listed below. There is no additional setup needed on the customer site for this to work. As customers prepare for the upgrade to Teams, they must consider deploying Teams native phones for a complete Teams experience.
