Downloading and Verifying Configurations
41
Once obtaining a provisioning server address in one of the ways introduced above, the
phone will connect to the provisioning server and download configuration files. During
the auto provisioning process, the 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 resource files need to be updated and the access URLs have been specified in
configuration files, the phone will then try to download and update the resource files.
After downloading, the phone resolves the configuration files, downloads the resource
files requested 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. 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 phone will complete the auto provisioning
without repeated update. This is used to avoid unnecessary restart and impact of
phone use.
If configuration files have been AES-encrypted, the phone will decrypt them after
downloading the configuration files. For more information on how the phone decrypts
configuration files, refer to
Yealink Configuration Encryption Tool User Guide .
The phone only reboots when there is at least a specific configuration requiring a reboot
during auto provisioning.
For more information on the specific configurations which require a reboot during auto
provisioning, refer to Description of Configuration Parameters in CFG Files on page 75 .
