Factory reset
Returning this phone to defaults
Steps
- On the phone: Menu, then Advanced (enter the admin password), then Reset to Factory Settings, then OK.
- This phone's admin password is set per device by this platform and is not the Yealink default. If you do not have it, contact support rather than guessing at the vendor default.
If it does not come up
- Confirm the phone has a network cable in the internet/PoE port, not the PC-passthrough port.
- Confirm the model recorded for this device matches the label on the phone exactly.
- Confirm a line is assigned to the device in the portal.
- If the phone previously worked elsewhere, factory reset it before enrolling.

Set the matching DHCP option once on your own network, and every Yealink phone you plug in after this one finds the platform on its own.
