Common Network Feature Codes for Australian Phones
Network feature codes are short codes used to manage features like call forwarding and call waiting directly from your phone's keypad. While most smartphones now have menu settings for these, the codes are still active and are a very useful tool for troubleshooting or for managing features on modern NBN and VoIP landline services.
