Polycom CX 3000 and Skype for Buisness Online



we want to use a Polycom CX3000 with Skype for Buisness Online.

When i type in my login information, the device doesn´t continue with its login process, while it says "connecting to Lync Server".

The latest firmware is installed and the required firewall ports are open.

I don´t know if this information helps you, but our complete IT infrastructure is based on Azure.

Do you need further information??


Greetings from Germany.

Hello @Gelenkwurm35,

Polycom and other manufacturers produce these optimized for Microsoft® Lync® or Skype® for Business devices after a reference design and the embedded OS running on the phones is provided, supported and maintained by our partner Microsoft®.

You therefore may want to reach out to the Microsoft® community and / or Microsoft® support directly instead as this is the most direct and efficient path.

Polycom is unable to add any new features into the functionality of these CX Devices

Please try here

Best Regards

Steffen Baier

The SfB account used needs to be licensed for Enterprise Voice. Microsoft Azure do not have this capability at present i guess.  Polycom and MS should be documenting this. I have found this link might useful: http://blog.schertz.name/2016/02/polycom-phones-with-skype-for-business-online/
