Phone Connections

Use an Ethernet cable to connect your phone to your LAN and enable the phone's full functionality. If your
Ethernet port is equipped with Power over Ethernet (PoE), you can power the phone through the LAN port.
Do not extend the LAN Ethernet cable outside the building. For your phone to work, it must be connected to
the IP telephony network.
