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.

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.
Wait for 15 Seconds
- Let the device fully power down.
Initiate the Reset
- While the base is still unplugged, press and hold the connect/pairing button on the front of the unit.
Power Back On (While Holding Button)
- While continuing to hold the button, plug the power adapter or network cable back in.
Wait for Green Lights
- Keep holding the connect button until all three LEDs turn solid green.
Release the Button
- Once you see the solid green lights, release the button.
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.

Hold Down the ‘OK’ Button
- Press and hold the OK button until the phone displays a prompt to reset.
Confirm the Prompt
- Select Yes or Confirm on the reset prompt screen.
Enter PIN (If Required)
- Default PINs are usually 0000 or 1379.
