I have used my phone for a year and it works great. However, I just moved and now need to connect through my computer but cannot get a connection. is there a setting I need to change besides changing the cord plug-in in the back of the phone?

Hi JL,


There are 2 Ethernet ports on the rear of most Polycom IP phones, one labeled "LAN/Network" and the other "Computer".

If I'm understanding your question correctly, you are attempting to connect your phone to the network through your computer? As this is a network device, this will not work. The phone must have its own Ethernet connection to your LAN for it to function.

Conversely, you CAN connect the computer to the back of the phone so the computer receives a network connection.


LAN----Phone---Computer will work fine



LAN---Computer---Phone will not work.


If the Computer port has been disabled, you can re-enable it in the phones menu interface: Menu, Settings, Advanced, Network.

Hello JL,


welcome to the Polycom Community.


As James explained above the usual setup would be for the Phone to be connected via an Ethernet Cable to your Switch/ Home Internet Router and the PC connected to your Phone.


Another Option could be that you have a USB Modem for your Internet Connection and used Internet Connection Sharing via the Ethernet Card in your PC to use the Phone.


As long as these details are unclear it is rather difficult to troubleshoot your issue.


Best regards
