Step 1: Identify your Exact Yealink T1 and T2 Phone Model and MAC Address

Be sure you follow the steps for the correct phone model. You can find the model and MAC address on the label at the back of the handset, or by pressing the “Menu or OK > Status” on the phone. Take a note of the MAC address, you will need this for the configuration.

Step 2: Add The Phone to the Extension

From the admin console in your web client:

  1. Go to “Users” and select the user you want to add a phone for.
  2. Click on the “IP Phone” tab. Click “Configure a phone” to add a phone.
  3. Now select your phone model from the dropdown menu.
  4. Enter the phone’s MAC address without dashes or colons, and click “Add phone”.

Step 3: Router Phone, SBC or LAN?

  1. If 3CX is on the cloud, you must use a router phone or SBC:
  1. If it is not a router phone you need to specify one or an SBC.
  2. If the device is a router phone, you can connect it directly as a router itself.
  1. If 3CX is on premise or self hosted, you have an additional option, you can select “Local LAN/VPN”.
  2. Click “Add Phone” to save the phone configuration for this extension.

Step 4: Connect the Phone

3CX will now create provisioning information for the phone and make these available on the provisioning URL. The phone must connect to this URL to retrieve its configuration information and authentication details. You have the following options:

  1. RPS - Connect the phone to the network within 14 days. If it is already connected, restart it. The phone will be configured automatically and restarted.
  2. PNP - If 3CX is on premise or connected via SBC, you can connect the phone to the LAN and look for it in the PNP dialog (Admin Console > Phones > PNP Phones). Right click and assign it to the extension you configured above.

Alternatively you can login to the phone's webUI and enter the URL manually. You can also use DHCP option 66.
