Question about Jabra DUPLIKAT Evolve 75 MS Duo

MS is optimised/zeroed for Microsoft Skype for Business (now Microsoft Teams). UC is for all other applications.

From the Jabra FAQ:

What is the difference between the ordinary UC models and the models certified for Microsoft Skype for Business?

With the models that are certified for Microsoft Skype for Business (or Microsoft Lync), you can use Microsoft Skype for Business via the plug-and-play function. Plug-and-play has the following advantages:

Automatic selection as the default audio device.
Call answer/end, volume control and mute functions.


If several certified audio devices are available, call prioritisation is also possible. Microsoft Skype for Business then transmits the sound to the appropriate device used for the incoming call.

If you are using a Microsoft Skype for Business certified model with another computer softphone client, the product should work exactly like a UC model in terms of audio and features (such as call answer/end, volume control and mute).

If you do not use Microsoft Skype for Business, please use the standard UC model.
