How to factory reset your Yealink handset (W Series & T Series)

Modified on Tue, 8 Jul at 5:37 AM

If your Yealink handset is acting up: frequent call drops, connectivity glitches, or just plain wonky behaviour, a factory reset might be just what it needs. Resetting restores the device to its original settings and can resolve most persistent issues.


This guide walks you through how to perform a factory reset on both Yealink W-Series (cordless) and T-Series (desk) phones.


Yealink W-Series (Cordless DECT Handsets — via Base Station)

Use this method if you're using a W70B or other Yealink DECT base station model.

  1. Power Down the Unit

    • Unplug the power adapter from the back of the base station.

    • If you're using Power over Ethernet (PoE), unplug the network cable instead.

  2. Wait for 15 Seconds

    • Let the device fully power down.

  3. Initiate the Reset

    • While the base is still unplugged, press and hold the connect/pairing button on the front of the unit.

  4. Power Back On (While Holding Button)

    • While continuing to hold the button, plug the power adapter or network cable back in.

  5. Wait for Green Lights

    • Keep holding the connect button until all three LEDs turn solid green.

  6. Release the Button

    • Once you see the solid green lights, release the button.

  7. Final Reboot

    • Wait 5 minutes for the reset to complete.

    • Then, unplug the unit again for 15 seconds and plug it back in to reboot.


Yealink T-Series (Wired Desk Phones)

Resetting a Yealink T-series phone is even easier, no power cycling is needed.

  1. Hold Down the ‘OK’ Button

    • Press and hold the OK button until the phone displays a prompt to reset.

  2. Confirm the Prompt

    • Select Yes or Confirm on the reset prompt screen.

  3. Enter PIN (If Required)

    • Default PINs are usually 0000 or 1379.

  4. Access the Web Interface

    • After reset, you may need to log in to the phone’s web interface.

    • Find the phone’s IP address in the Settings menu, then enter it in your web browser.
