## Procedure

**Before You Begin!**

These steps are generally intended for reusing Yealink phones with 8x8 service. You can reuse existing Yealink phones with 8x8 service as long as they are a supported model with **a valid factory-installed device certificate**.

It's crucial that Yealink certificates are factory-installed and not added later. 8x8 supports only the Yealink phone models listed [**here**](http://www.8x8.com/products/devices/compatibility). If you are not sure which model phone you have, please check the underside of the phone. The model number is listed on the label on the bottom of the phone.

*Accommodation of devices not purchased from or originally provisioned for service by 8x8 is on a commercially reasonable effort basis. These devices are not guaranteed to be supported on 8x8 service.*

### Check for Device Certificate

In order to work with 8x8 phone service, your Yealink phone must have a valid factory-installed security certificate, also known as a device certificate. Follow these steps to determine whether a valid factory-installed Device Certificate is present on your phone.

1. On the phone, press **OK**.
2. Scroll down and select **More**.
3. Select **Phone**.
4. Scroll down to **Device Certificate**.
5. Read the displayed message.
  - If the message says **Device Certificate: Factory Installed**, your phone is supported on 8x8 service.
  - If the message says **Device Certificate: Not Installed**, **Device Certificate: Invalid**, or if there is no device certificate message at all, then the phone is not supported on 8x8 service.

#### Configure the Phone

After checking the device certificate, verify that the device has the recommended firmware installed (see recommended firmware Once this is verified, you can move on to configuring the phone.

### Reset Phone to Factory Defaults Through the Phone's Web GUI

The device web interface (GUI) allows you make changes to the phone's settings via a web browser on your computer, which can often be more convenient than on the phone screen itself. You must ensure that:

- The phone is plugged into your network.
- The computer is connected to the same network as the phone.

1. Locate the phone's IP address by going to **Menu** > **Status** > **IPv4** on the phone.
2. In a web browser on a computer on the same network as the phone, browse to the phone's IP address.
3. Log in as *admin* and enter the phone's MAC password. ![YealinkGUILoginScreen-300x227.png](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/9299)
