Provisioning a Yealink T20, T22, T26, T28, T32, T38 for 3CX Phone System

This guide has been tested for the following phone models:
Yealink T20(P), T22(P), T26(P) and T28(P) with firmware version X.61.0.70
Yealink T32(G) and T38(G) with firmware version X.0.0.115.

The easiest way to set up a Yealink phone for use with 3CX Phone System is to use the built-in plug and play provisioning functionality inside 3CX Phone System. This will allow the phone to configure itself by retrieving a 3CX-generated phone configuration file. Alternatively you can configure using DHCP and option 66.  For more information, see this configuration guide.

Step 1: Verify Firmware Installed on your Phone

Verify the firmware version currently installed on the phone as older firmwares will not have the plug and play feature. To do this power up the phone and click on Menu > Status > Firmware. Go to Yealink Support Website to download the latest firmware for your phone.

Step 2: Plug Phone into the Network

Plug your Yealink phone into your LAN. (The Phone must be on the same LAN as that of the 3CX Phone System IP PBX).

Step 3: Approve Phone and Assign an Extension

Now you need to approve the IP Phone registration and assign an extension. To do this

  1. In the 3CX Management Console, go the "Phones node"
  2. The phone you just plugged in will appear at the top of the list in bold.
  3. Now right click on the IP Phone and select from 2 available options:
    • "Add Extension" - this will create a new extension.
    • "Assign to existing extension" - this will assign an existing extension.
  4. Now Assign or Create an extension and click 'OK'.
  5. You will be taken to the "Edit Extension" settings page
  6. You can now optionally configure BLF keys or speed dials. For information, see Step 4 below.
  7. Click OK. 3CX Phone System will send a provisioning link to the phone. The phone will reboot and apply the configuration. The phone will be ready for use after that.

Step 4: Optional - Configure BLF function keys

This section applies to T26, T28 and T38 phone models as these phones have function keys that can be provisioned through the 3CX Plug and Play feature. This can be done from the "Phone Provisioning" tab in the extension settings.

  1. In the Edit Extension page, navigate to the 'Phone Provisioning' tab
  2. Select codec priority and phone LCD display language  
  3. Configure function keys for BLF, Shared Parking and various types of Speed Dials
  4. Click 'OK'. The phone will reboot and provision automatically.

Congratulations! You have configured a new Yealink phone using the 3CX Plug and Play feature.
