The parameters in the newly downloaded configuration files will override the same parameters in files downloaded
earlier.
Note: For the phone running firmware version 82 or earlier, it downloads configuration files referenced in the boot
file in sequence.
For the phone running firmware version 83 or later, “static.specific_model.excluded_mode determines which con-
figuration files referenced in the boot file to be downloaded.
Provisioning Methods
Yealink provides two ways to provision your phones:
l Manual Provisioning: provisioning via the local phone user interface or web user interface.
l Central Provisioning: provisioning through configuration files stored in a central provisioning server.
The method you use depends on how many phones need to be deployed and what features and settings to be con-
figured. Manual provisioning on the web or phone user interface does not contain all of the phone settings avail-
able with the centralized method. You can use the web user interface method in conjunction with a central
provisioning method and phone user interface method. We recommend using centralized provisioning as your
primary provisioning method when provisioning multiple phones.
