static.auto_provision.local_contact.backup.path
String
Blank
Description:
Configures a path or URL for the IP phone to upload/download the <MAC>-contact.xml
file.
If it is left blank, the IP phone connects to the provisioning server URL, and
uploads/downloads the contact file “<MAC>-contact.xml”.
Example:
static.auto_provision.local_contact.backup.path = http://192.168.1.20/contact
Once the contacts update, the IP phone will upload the contact file to the specified path
“http://192.168.1.20/contact”.
During the auto provisioning process, the IP phone downloads the contact file “<MAC>-
contact.xml” from the specified path “http://192.168.1.20/contact”.
Note: It works only if the value of the parameter
“static.auto_provision.local_contact.backup.enable” is set to 1 (Enabled).
