Feature codes are short numbers used to call a particular telephone line, hunt group, etc, from within the system. For example, you can set "123" to forward to a hunt group of all telephone lines.

Feature codes are also used to access features such as voice mail. For example, *1 is often set to allow direct access to voice mail without a password, and *2 asks for a mailbox and password.

You may change these assignments; this is useful if your staff are used to the feature codes of a legacy PBX system.
