Beginning in PBX software version 5.2.1-10, we have begun including more integrated support for Yealink phones. They can now be found via autodiscovery and assigned to extensions, although they do not currently respond to configure or restart commands. Yealink phones CAN autoprovision from the pbx once assigned, however, by either logging into each phone's webGUI, or using our quick setup utility. The quick setup utility can be downloaded here Yealink Quick Setup utility


Auto Provisioning a Yealink Phone

You must assign a phone to an extension either manually or using Auto-Discovery:

Manual – Navigate to Destinations -> Extensions -> Edit Extension -> Advanced and enter the MAC address of the phone into the “Phone MAC:” field.  SAVE CHANGES then APPLY CHANGES.


Auto Discovery - If the phones are on the same LAN as the PBX you can use Auto Discovery. Navigate to Destinations -> Extensions. Click the “Auto-Discovery” tab at the top, and then click “Auto-Discovery (scan network)”


Once the scan has completed:

1. Select the extension you would like to assign to the Yealink phone(s) from the drop down list.

2. Check the box next to each Yealink phone you are assigning.

3. Click the Assign button.

This will automate the process of entering the Yealink phone’s MAC address into each extensions Phone MAC field in it’s advanced settings section.

►Yealink phones shown in the Auto Discovery section will not show up colored green even though they may well be assigned and using the PBX.  The coloring is merely cosmetic and will not affect the operation of the phone.

Once the phones are assigned to extensions they can now be provisioned, either manually or if the phones are on the same LAN as the PBX the Quick Setup utility can be used.

  • Log into the GUI interface of phone via its IP Address (user: admin/pass:admin)
  • Navigate to Settings=>Auto Provision
  • If the phone is local: Set Server URL to
    TFTP://<IP address of pbx>/
  • If the phone is remote: Set server URL to
    http://<public IP address of pbx>/ippbx/phonecfg/
  • If the phone is remote: Set the username to admin, and the password to 1234
  • Click Confirm at the bottom of the page
  • Click Auto Provision Now

The phone's screen should change to indicate that it is updating its config, and will then register if successful.

Quick Setup Guide

Use this in conjunction with the quick setup utility

http://admin:1234@<public IP of PBX>/ippbx/phonecfg

Additional programming tips:


  • When configuring the Park key manually, set the type to DTMF, and the value to ##700#.
  • When configuring a Record key manually, set the type to DTMF, and the value to *#
  • When configuring the Day/Night key manually, set the type to BLF and the value to ff.
  • Under the DDS key tab is a link for Line Keys. Be sure to set the Line Keys to Account 1 if you want them to function as a line key, otherwise you can configure them just like any other programmable key.
  • Yealink Phones - Blind BLF transfers to voicemail
    Use a prefix key on the Yealink phones to handle blind transfers directly to a BLF extensions voicemail.
    Key Type: Prefix     Label: VM Xfer     Value: *
    While on the call press: TRANSFER -> VM Xfer -> BLF of the extension -> TRANSFER
  • EXP20 Expansion module for Yealink T2 Series phones - Key #1 AND Key #21 must be left blank in order for the Page Switch to work properly.


To set up multicast on your Yealink phone:

  • Log into the GUI interface of phone via its IP Address (user: admin/pass:admin)
  • Navigate to Contacts=>MulticastIP
  • Populate the Listening Address field with the mutlicast IP of the multicast group built in the PBX, followed by a colon and the port configured for the group.
    • eg.
  • Populate the Label field with a name that will display on the LCD when paged by the multicast group
  • Click the Confirm key and your settings will be saved, allowing the phone to receive multicast pages.

A dealer has brought to our attention this link to a Yealink forum that has a firmware for multicast. I know in our testing, the .143 version had the settings needed. But its possible you may need this version as that is what the dealer needed, so we are linking to the information.

Phonebook files

Yealink phones use a specific XML format for phonebook files.

Here is an example, red text can be changed:

<?xml version="1.0" encoding="UTF-8"?>

      <Name>Spanky McFarland</Name>


      <Name>Alfalfa Switzer</Name>



  • T38G firmware version fixes an issue with Parked calls bonding with other calls incorrectly.  Extract the .rom from the Zip folder and load it into the phone.

Yealink Documentation

The T29 guide covers basic usage of the entire T2 series of Yealink phones.  The T48 guide covers basic usage of the entire T4 series of Yealink phones.
