Hi,
Hoping can answer my question, I have had no luck using the search facility.
I have a CX3000 conference phone, I would like to use the phone via a desktop PC USB connection only. i.e. the CX3000 is not connected to our network LAN, only to a desktop PC running Lync client (2010 version) via USB cable.
The phone powers up (via power supply), the PC detects the CX3000, I log into Lync desktop client, I authenticate on the PC Lync client, but the CX3000 displays the following message:
Signing in....
Network cable was not detected. Please check that your cable is connected to the network port and that you have a network connection'
It seems the phone is requiring a network LAN connection to authenticate to the Lync server itself rather than through the desktop PC Lync client. I was hoping the CX3000 conference phone would operate how a CX300 USB phone does and just authenticate via the PC Lync client (USB cable).
Apologies for the long explanation. The question is can a CX3000 operate via PC USB connection only, or does it also require a network LAN connection?
Thank you
Mike

Hello Mike,
Polycom and other manufacturers produce these optimized for Microsoft® Lync® 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.
To my knowledge the CX3000 like the CX600 is not a USB Speaker / Microphone like the CX100/CX200/CX300 and requires therefore a Ethernet connection to work.

Thanks Steffen, you have confirmed what I thought was the case.
I don't suspose there is a Polycom conference phone model which operates as per a CX300 (mircophone / speaker) is there? I cannot see one.

Mike
