Remote Phone Book
The remote phone book is a centrally maintained phone book, stored on the remote server. Users only need the
access URL of the remote phone book. The IP phone can establish a connection with the remote server and down-
load the phone book, and then display the remote phone book entries on the phone.
Yealink phones support up to 5 remote phone books. The remote phone book is customizable.
Note: For T40P/T40G/T23P/T23G/T21(P) E2/T19(P) E2 phones, we recommend that you download less than 3000 remote
contacts (including one name and three numbers fields) from the remote server. For other phones, we recommend that you
download less than 5000 remote contacts (including one name and three numbers fields) from the remote server.

Remote Phone Book File Elements
Yealink phones support two template files: Menu.xml and Department.xml.
The Menu.xml file defines the group/department of a remote phone book. The Department.xml file defines contact
lists for a department/group, which is nested in Menu.xml file.
The following table lists the elements you can use to add groups or contacts in the remote phone book file. We
recommend that you do not edit these elements.
