Occasionally it is necessary to factory reset during troubleshooting and provisioning IP devices connected to VoIP phone systems.  Factory resetting is an alternative quick fix if a device is not working properly or if you are looking to follow an online guide from the same starting point. However, do be careful because all the localized settings on the device will be deleted when you factory reset.  See below for directions on factory resetting Yealink, Cisco, Polycom, Grandstream and Patton VoIP products.
