Using Feature Codes
Most features are used by dialing a feature code — a 1-, 2-, or 3-digit number preceded by #. Others — Hold, Transfer, and Conference — are used by pressing Recall or Flash or a switchhook flash and do not have a feature code. Feature codes can be used only with touch-tone telephones. This chapter provides general instructions for using features and information on customizing your telephone. Detailed instructions for using specific features are provided in Chapter 5.
