Downloading and Updating Configuration Files

After obtaining the provisioning server address in one of the ways introduced above,

the phone will request to download the configuration files from the provisioning server

when it is triggered to perform auto provisioning. During the auto provisioning process,

the phone will try to download the y000000000025.cfg file firstly, and then the

<MAC>.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 and

update the resource files.

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 phone will reboot to make the configurations effective after the auto

provisioning process is completed.

The phone calculates the MD5 values of the downloaded files before updating them. If

the MD5 values of the y000000000025.cfg and <MAC>.cfg configuration files are the

same as those of the last downloaded configuration files, this means that these two

configuration files on the provisioning server are not changed. The phone will complete

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.

If the configuration files have been AES encrypted, the phone uses the Common AES

key to decrypt the y000000000025.cfg file and the MAC-Oriented AES key to decrypt the

<MAC>.cfg file after downloading the configuration files.

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 reboot

after auto provisioning. If you want to force the IP phone to perform a reboot after auto

provisioning, you can configure “auto_provision.reboot_force.enable = 1” in the

configuration file.

For more information on the specific configurations which require reboot during

provisioning and the parameter “auto_provision.reboot_force.enable”, refer to the

section Description of Configuration Parameters in CFG Files on page 69.
