If your desk phone won’t turn on, it’s most likely an issue with your power supply. With VoIP, there are several ways to power your desk phone.

1. Power Cable: Plugging into the wall, and directly into the phone.

2. POE Injector: This small device plugs into a power source (often under the desk) and has 2 internet ports, one for network, and one for the phone. Make sure the cables are plugged into the correct ports. There is either icons, or labels. The phone should be plugged into the one titled “POE.”

3. POE Switch: This is a network device that supplies power to the internet cables plugged in. This is often centralized in the data-closet.

After confirming you have a power source, the next steps are to confirm each cable is connected properly. If other phones in the office are working, you can compare the setup of phones that are working properly.
