Hello
The screenshots that you shared are being audited, in the meantime I will share a guide for setting the parameters related to the remote phone book on the IP phone's web page:
a. Log in to the IP phone's web page.
b. Click the Contacts tab, and click Remote PhoneBook. Set Phone Book Url and Phone Book Name, as shown in the Figure.
c. The Phone Book Url parameter indicates the URL for downloading the file, for example,http://192.169.1.21:80/Menu.xml. The Phone Book Name parameter indicates the name to be displayed on the IP phone's LCD. You can set Phone Book Name to any value, for example, Company.
A total of five remote phone books are supported by eSpace 7870, 7850, 7830 and 7820.

d. Click Confirm.
Please let us know if it works
Thanks
