Across the Telstra & Optus networks here in Australia, there are a number of network feature codes that allow you – or your phone technician – to make network level changes to your phone lines.

These network features include things like turning call waiting on or off, enabling and disabling call forwarding, or blocking your outbound caller ID.

Below you will find a number of tables which covers the Optus and Telstra network feature codes, broken into the following categories:
