Whenever the system receives a set of digits to process, if those digits do not match a user or group extension number, the system will look for a short code match. The matching short code then defines what action (short code feature) should be applied to the call, where it should be routed and which of the dialed digits, if any, should be used in the subsequent action.
This applies to digits dialed by a telephone user, sent by a user selecting a directory contact or speed dial, and in some cases to digits received with an incoming call on a line.
This section provides an overview of short codes configuration and use.
