auto provisioning.
The contact file is named after the MAC address of the IP phone. MAC address, a unique 12-
digit serial number assigned to each phone, can be obtained from the bar code on the back of
the IP phone. For example, if the MAC address of an IP phone is 00156574B150, the name of
the contact file is 00156574b150-contact.xml (case-sensitive).
Procedure
Backing up the local contact file can be configured using the configuration files.
Central Provisioning
(Configuration File)
Details of the Configuration Parameters:
static.auto_provision.local_contact.backup.enable
Description:
Enables or disables the IP phone to upload the <MAC>-contact.xml file to the server each
time the contacts update and download the <MAC>-contact.xml file from the server during
auto provisioning.
0-Disabled
1-Enabled
If it is set to 0 (Disabled), the IP phone does not upload the contact file "<MAC>-
contact.xml" to the server, so the IP phone downloads the contacts in the "contact.xml"
from the access URL configured by the parameter "local_contact.data.url" or
"local_contact.data_photo_tar.url" during auto provisioning.
If it is set to 1 (Enabled), the IP phone uploads the contact file "<MAC>-contact.xml" to the
specific path configured by the parameter "static.auto_provision.local_contact.backup.path"
each time the contacts update; and downloads the contacts in the "<MAC>-contact.xml"
according to its MAC address from the specific path during auto provisioning.
Note: It does not affect the downloading of the contact avatar/icon files.
