# About the Phone Book Directory

The MiVoice Business Console supports two modes of operation for Phone Book Directory search and console display purposes.

- MiVoice Business Directory mode – this is the default mode of operation of the console. See About MiVoice Business Directory Mode for more information.

- Additional Database Fields (ADF) Directory mode – this is an enhanced directory capability that the console can use instead of using the default MiVoice Business Directory. See About ADF Directory Mode for more information.
