The following figure shows a portion of a lang formatted English language file:
####################################################
## Configure the custom LCD language file ##
####################################################
#Specify the access URL of the custom LCD language file.
gui_lang.url =
If you want to modify the existing language translation for the IP phone user interface,
edit the language translation and then configure the parameter “gui_lang.url =” in the
configuration file, for example:
gui_lang.url = tftp://192.168.1.100/000.GUI.English.lang
During the auto provisioning process, the IP phone connects to the provisioning server
“192.168.1.100”, and downloads the language file “000.GUI.English.lang”. The
language translation will be changed accordingly.
