How do I create a phone book with User Profiles for Confluence?

To realize a phone book, you can use the Profile List macro with the criteria

Telefon:[0 TO 9]

Telefon is the name of the field containing the phone number.

So what you need to do, is simply adapt the filter criteria to your needs.

You can use the parameter Style to determine if you want to display the information as a table or profile cards and Display mode to define the user profile fields you want to display. There are additional options for the Profile List macro which are described in detail in the User Guide.
