Although the Jabra Speak2 55 MS, the version certified for Microsoft Teams, is primarily optimised for Microsoft Teams, it is also compatible with other Unified Communications (UC) platforms, albeit with some limitations.

- The Speak2 55 MS offers plug-and-play functionality specifically for Microsoft Teams, which means it works best with Microsoft Teams.
- For use with other UC platforms such as Skype for Business, Zoom or Google Meet, Jabra recommends the UC variant of the Speak2 series, as it is certified for all common UC platforms.

So if you want to switch flexibly between different UC tools such as Skype for Business and Zoom, the UC version of the Speak2 55 would be the better choice.
