The majority of the end-user functionality can be accessed via feature codes. A feature code is a number that you dial on a handset, that will perform a function on the phone system - sometimes unique to that handset.
The following is the built-in list of standard feature code. Some applications such as Call Flows will generate additional feature codes.
