The setting is disabled by default. If the UDP communication is blocked by your router and you enable the setting, the network can be stabled.
Note: When you'd like to use the UPnP Port Mapping in iOS 14 or later, go to "Settings" on the device > "SkyPhone" > Enable access to "Local Network." If the access is disabled, it is possible that you cannot start calling correctly.
