Upload the wallpaper image to the provisioning server and then specify the access URL
in the configuration file:
####################################################
## Configure the access URL of the wallpaper ##
####################################################
wallpaper_upload.url =
For example, enter “tftp://192.168.1.100/wallpaper.jpg” in the “wallpaper_upload.url =”
field. During the auto provisioning process, the phone connects to the provisioning
server “192.168.1.100”, and downloads the wallpaper image “wallpaper.jpg”.
To use the custom wallpaper, you also need to configure the following parameter.
#Configure the custom image (e.g., wallpaper.jpg) as phone wallpaper.
phone_setting.backgrounds = Config:wallpaper.jpg
The IP phones allow you to upload contact data in batch via auto provisioning. You can
create multiple contacts using the supplied local contact template file.
When editing the local contact template file, learn the following:
 Add groups between <root_group> and </root_group>.
 Add local contacts between <root_contact> and </root_contact>.
 When specifying the desired line for the contact, valid values are -1 and 0~5, -1
stands for Auto, and 0~5 stand for line1~line6.
 When specifying a ringtone for the contact and the group, valid values are Auto,
Resource:RingN.wav (system ringtone, integer N ranges from 1 to 8) and
Custom:Name.wav (customized ringtone).
 When specifying the group for the contact, valid values are the group names
(existing or added groups).
To customize a local contact file:
1. Open the template file using an ASCII editor.
2. For each group that you wish to add, add the following string to the file. Each starts
on a separate line:
<group display_name=”” ring=””/>
