Hello VoIP Phones
Good day and thanks for reaching out.
Microsoft does provide a public preview for various Teams features. However, details specifically about Teams phones may not be explicitly
available in the documentation. The general information indicates that preview features are accessible, but coverage may vary depending on the
specific type (Teams desktop, mobile, or phone).
To get preview updates- Get early access to new features in Microsoft Teams - Microsoft Support
To enable preview update policies. Public preview in Microsoft Teams - Microsoft Teams | Microsoft Learn
Hope this helps! Please feel free to repost if you have further queries.
Sincerely,
Bertrand
