Learn how to store your contacts in the main phone book and link to your macOS address book or use a plugin to link to Windows Outlook.

Storing contacts centrally

You can either store and manage your contacts directly on the cordless HD-Phone or centrally on your router. This ensures that all of your contacts are stored in a safe place, even if you change your phone.

Synchronising contacts

Synchronise your main phone book and connect contacts with your Windows Outlook or macOS contacts. Your contacts will then all be listed in Outlook/macOS well as on your phones.


The Business Telephony and Business Communication mobile app does not support contact synchronisation of the main phone book because the LDAP interface for contact lookup is not supported. Your alternative

Windows Outlook Plugin

Downloading the plugin

  1. To download, go to this page.
  2. Click Download and follow the instructions of your Internet browser.
  3. Close Outlook before starting the installation.


Requirement: Windows 7 (SP1), Windows 8.1 or Windows 10 operating system and Outlook version 2013 or higher. Windows Vista, Windows XP and Windows 8 are not supported because .NET Framework 4.8 is set as a minimum requirement.

    If you have more than one location, select the location where you want to allow the authorisation. This will synchronise your phonebook contacts with the selected Outlook folder. Close all windows to continue.To select a different location later, a new synchronisation profile must be created. If your product is a Smart Business Connect, this will not be displayed. No location selection is necessary.

    Check under “Display” that groups are visible – it will say “Hide group” if this is the case.

    Schritt 4

    The attributes “First name”, “Last name”, “Mobile”, “Private” and “Work” will be synchronised.

Entry in the telephone book

Would you like people to be able to look you up in the public phone book? An entry in the official directory ensures your phone number and address are listed in both the printed and electronic phone book. You can register your number and address online and edit or add to the entry at any time (e.g. when you change address, get married, have children etc.).
