CUSTOMIZED LCD SCREEN & XML
With its graphical LCD screen, soft-keys and XML-support, the GXP is a highly customizable phone. XML is
used to communicate between web-servers and the GXP to dynamically update the phone’s phonebook and
idle screen logo and functions.
XML Phonebook
The Grandstream GXP enables you to easily share and maintain a phonebook through the web. The XML-
phonebook must be stored on a web-server. For more information on how to setup the phone to download the
phonebook, please see the
Configuration with Web Browser. For more information on how to create a
downloadable XML phonebook, detailed information and configuration guides are located on the website in the
