Yealink Phone Steps
Certain models may have a slightly different look, but your steps should overall be the same.
Plug your phone into your local network by connecting an ethernet cable into the port labeled Internet on the back of the phone and the other end to your wall jack. (If your network has PoE, your phone should power on now and you can skip to step 3). If your computer needs to be connected to an ethernet cable or you only have 1 wall jack, plug an ethernet cable from the PC port on the phone to your computers ethernet port.
Plug the power cable into the phone and into a power outlet.
Let the phone boot up completely to the home screen.
Press the OK button on the phone to retrieve the IP address for the phone. It will be listed under the section labeled IPv4. If it is blank or shows 0.0.0.0 you may need to troubleshoot your local network.
Open up your web browser or a new tab in an existing browser window on your computer and enter the IPv4 address in the address bar at the top.
