Yealink T29G/T27G/T53W: Factory Reset Desktop Phone
A factory reset is a "last resort" in your troubleshooting; it is a master reset to restore the device to its original system state by erasing all of the information stored on the device in an attempt to restore the device's software to its original manufacturer settings.
WARNING: A factory reset will delete all user saved information, such as contacts in Phonebook. Please do NOT factory reset your device unless expressly asked to by a support engineer.
