Your phone can receive power either via the power adapter included with the phone or by using Power over Ethernet (PoE).
If you are using the power adapter, plug the adapter into a standard wall outlet and the other end into the phone's power port.
If using PoE, skip to Step 3.
3. Connect to the internet.
Using the ethernet cable, connect the network port of the phone to the network port on your router or network wall outlet that connects to the internet.
If you're using Power over Ethernet (PoE) to power the phone, make sure the PoE switch is connected to the network.
You can also connect using WiFi under the phone settings menu if it is supported by your phone, however, RingCentral recommends connecting to your network with an ethernet cable due to the varying reliability of WiFi signals.
