Downloading and Verifying Configurations

Downloading Boot Files and Configuration Files

After obtaining the provisioning server address in one of the ways introduced above, the phone
will request to download the boot files and configuration files from the provisioning server when
it is triggered to perform auto provisioning.
The IP phone will try to download the MAC-Oriented boot file firstly and then download the
configuration files referenced in the MAC-Oriented boot file in sequence from the provisioning
server during the auto provisioning process. If no MAC-Oriented boot file is found, the IP phone
will try to download the common boot file and then download the configuration files referenced
in the common boot file in sequence. If no common boot file is found, the IP phone will try to
download the Common CFG file firstly, and then try to download the MAC-Oriented CFG file
from the provisioning server.
If the access URLs of the resource files have been specified in the configuration files, the phone
will try to download the resource files.

Resolving and Updating Configurations

After downloading, the phone resolves the configuration files and resource files (if specified in
the configuration files), and then updates the configurations and resource files to the phone
flash. Generally, updated configurations will automatically take effect after the auto provisioning
process is completed. For update of some specific configurations which require a reboot before
taking effect, for example, network configurations, the IP phone will reboot to make the
configurations effective after the auto provisioning process is completed.
The IP phone calculates the MD5 values of the downloaded files before updating them. If the
MD5 values of the Common and MAC-Oriented configuration files are the same as those of the
last downloaded configuration files, this means these two configuration files on the provisioning
server are not changed. The IP phone will complete the auto provisioning without repeated
update. This is used to avoid unnecessary restart and impact of phone use. On the contrary, the
IP phone will update configurations.
The latest values to be applied to the IP phone are the values that take effect.
The phone only reboots when there is at least a specific configuration requiring a reboot after
auto provisioning. If you want to force the IP phone to perform a reboot after auto provisioning,
you can configure "static.auto_provision.reboot_force.enable = 1" in the configuration file.
For more information on the specific configurations which require a reboot during auto
provisioning and the parameter "static.auto_provision.reboot_force.enable", refer to
