There are times when it is necessary to reset the phone, such as to accept new settings or to attempt to register the phone with the network. Resetting the phone does not erase the user’s personal configurations. It only reloads the firmware and any updates from the network server. If there are no updates available, none of the settings should change from the previous state. It does renegotiate IP address and DHCP settings, so these items may change from the previous state.
Restoring Factory Defaults
It is possible to erase configuration settings on a phone and restore it to the state that is was received from the factory. Keep in mind that using the Factory option will erase all settings customized locally at the phone, such as personal speed dial entries, phone book entries, line key settings, and distinctive rings. Any customization that is completed and delivered from the network server will be retained as these are provided when the phone reloads at startup.
