How to Factory Reset Yealink, Cisco, Polycom, Grandstream, 2N, & Patton VoIP devices

A common practice when troubleshooting and provisioning IP devices connected to VoIP Phone Systems is the factory reset, or a full restoration of an electronic device to its factory settings. People who factory reset phones include value added resellers, service providers, technicians, support staff, and even end users.

It is important to understand that while factory resetting a device is a great backup plan if a device is not working properly or if you want to follow a guide online and need to quickly get to the same starting point as the author, all of the localized settings on the device are lost when you factory reset. While 3CX and other capable phone systems can reconfigure your devices with auto provisioning or configuration files that can be easily reapplied to the device, it is important to remember to do so.
