Hi,
I have an older CX600 IP phone that has firmware that cannot connect to SfB and I do not have an on-premise Lync server. Is there a way to update the firmware on this phone without the on-premise server?
It has v4.0.7457.0
The USB connection fails, signing in on the phone fails.
Thanks for any help
Hello eugp,
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
