Problem connecting vvx 400 to Dell laptop

Hi, Our company has been using Microsoft Lync and we are moving to Skype for Business. With Lync we use a telephone or earpiece that is connected via USB and in Lync we have setup the configuration to use the phone (in office) or earpiece (when roaming).


As I work at home quite often, I decided to buy my own telephone to use instead of the earpiece and bought the VVX 400 as this was reasonably priced and certified for both Lync and Skype for Business.


I have troubles connecting the VVX 400 to the pc. It does not have USB ports and when connecting the ethernet cable to my laptop, the laptop decides that I'm connecting the network and it loses the wifi signal.


Is there a way to get by this problem or do I need another telephone ?

Hello sparrow147,

welcome to the Polycom Community.

The VVX Business Media Phones, unlike the CX USB range, are Voice over IP Phones which require a Ethernet connection to work with either LYNC / Skype for Business or OpenSIP.


These are not USB Phones and they work without a PC.


If you plug a Ethernet cable into the Ethernet PC port of the phone and connect it to the Laptop the Laptop will establish an additional network connection via the Phone.


You can use the BToE / Better together over Ethernet application to sync your LYNC / Skype for Business Credentials and therefor cause the phone to login to LYNC / Skype for Business.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
