Yealink – Reset Telephone to Factory Defaults

Resetting a Yealink phone to factory default restores the device to its original out-of-the-box settings. This process removes all user-specific configurations, including:

• SIP account registrations

• Network settings (static IP, VLAN, etc.)

• Custom ring tones and preferences

• Provisioning server details

• Administrator passwords

Steps

1. On the phone, press and hold the OK button for about 15 seconds.
   Note: For T57 Series, hold the Redial button for 15 seconds.

2. The display will change to Factory Reset ?
3. Select the Yes softkey
4. Select the OK softkey
5. The telephone will reboot.

If you are setup for auto-provisioning your phone will reconfigure itself.

If you do not have auto-provisioning you can now access the phone with default username and password.
