Reset a Yealink phone to factory settings

Last updated View as Markdown (opens in a new tab)

Wipe a Yealink desk, DECT or Teams phone back to its factory settings from the web interface or the phone.

A factory reset erases every setting on the phone, including its SIP account. Use it when:

  • the phone isn’t working properly and nothing else has helped;
  • you’re setting up a used or second-hand phone, or one you’ve unboxed and started before;
  • you’re giving away or selling the phone, and want to remove your details.

An auto-provisioned phone downloads its settings again after the reset. A manually set up phone needs its SIP details entered again.
