Knowledge Base - Factory resetting a Yealink desk or conference phone

BitBlock supported phones automatically re-provision following a factory reset provided they have access to the Internet

CAUTION - Factory resetting your phone removes all settings and restores your phone to a "like new" configuration. Be sure to back up any settings you require. Only continue if recommended by your support technician or if you have no concerns for data loss or loss of phone service.

Sometimes there is a configuration issue or other conflict that can be difficult to resolve. In these cases, it might be recommended to go back to a known good configuration. This can be accomplished by a factory reset. After a factory reset, the phones will automatically recover their programming (excepting any user made settings such as ring tones or speed dials). If a factory reset does not resolve the issue, it can be a way of proving a network fault.

Factory resetting a Yealink phone is a simple procedure:

Locate the OK key.
Press and hold the OK key until you see a prompt on the screen.
Press the OK soft key (below the screen) to confirm the reboot.
Wait for the reboot to complete.
Your phone may update its configuration after the reboot which may result in a second reboot process automatically within a minute or two of the first reboot.

If the reason for your reboot is related to difficulty in updating your configuration, this step should resolve the issue.

If your phone is a CP960, you can long press the circle button (12-15 seconds) while the screen is off or the left mute button to accomplish the same affect as there is no OK button.
