Hello Alex H,
The CX600 is LYNC / Skype for Business only and Ringcentral as far as I know is SIP.
You cannot use the CX600 for Ringcentral SIP
In regards to the CX600 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
