On the odd occasion, we find ourselves having to use advanced features on Telstra service landlines. Finding these numbers is often time consuming and what's worse, trying to remember those exchange numbers you USE to know is frustrating.
This is why we've compiled my own list of Exchange Feature codes. Please let us know if we have missed additional numbers that should be included. (VoIP Service Providers aren't covered below and if you're looking for Mobile GSM/2G/3G Network Feature Codes try here.)
