Example: Adding Contacts Using a Contact File
The following example shows the configuration for customizing a local contact file.
Customize the contact file “contact.xml” and place the contact file “contact.xml” and custom contact source (avatars
or icons) to the provisioning server “http://192.168.10.25”.
Example
local_contact.photo.url = http://192.168.10.25/Lily_photo.jpg
local_contact.data.url = tftp://192.168.10.25/contact.xml
During auto provisioning, the phone connects to the provisioning server “192.168.10.25”, and downloads the local
contact file “contact.xml” and an avatar “Lily_photo.jpg”. You can view the contacts on their phone, and specify the
avatar “Lily_photo.jpg” for a contact.
On T57W/T48U/T48S/T48G phones, when uploading a contact avatar, you can also upload a contact icon named
the same as this avatar, since a one-to-one correspondence between the icon and avatar. For example, an icon file
and avatar file both named ”Lily_photo.jpg” are available on the phone, the contact with specified default_pho-
to="Lily_photo.jpg" will use the corresponding name ”Lily_photo.jpg” as directory icon and avatar display.
The following shows the custom contact Lily with corresponding avatar and icon display:
Note: If you have configured to back up the local contacts to the server, the phone will download the contact file “<MAC>-con-
tact.xml” from the backup path from the server and display the downloaded contacts in the local directory list. The contacts in
the local contact file “contact.xml” downloaded from the provisioning server do not take effect.
