Exchange Phone Book


The telephones use central phone books: The data are synchronized with your personal contact data of the central Exchange server. This synchronisation runs every 4 hours and overwrites your local phone book.

Please note that the local phone book is also overwritten if your central phone book is empty or not configured.
