What is the "Use UPnP Port Mapping" in "Advanced Settings"?

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.
