# Manually Provision a Yealink T23P or T46G Phone Without GUI

## Objective

Manually provision a Yealink T23P or T46G phone.

## Applies To

- Yealink 23P and T46G devices

## Procedure

It is best practice to perform a factory reset when manually provisioning a phone.

### 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 [What is the recommended firmware for 8x8 phones and analog adapters?](/support/docs/what-is-the-recommended-firmware-for-8x8-phones-and-analog-adapters) Once this is verified, you can move on to configuring the phone.
