Hello @MRC ,
Welcome to the Poly Community.
I am unsure if this is a joke question or some sort of spam but your Email address seems from a valid organization so I am trying to be helpful here.
The CX Phone series is end of sale and end of support. They where created for LYNC and then you could use them with Skype for Business on premise or Skype for Business online.
Since 2018 Microsoft no longer supports them for S4B online now the Microsoft Teams 3PIP gateway.
A good article outlining why you should no longer use these old phones can be found >here<
In regards to where or how you can get Microsoft LYNC or Microsoft Skype for Business would require you to contact our partner Microsoft and/or a Microsoft-focused forum.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
