The parameters in the new downloaded configuration files will override the duplicate
parameters in files downloaded earlier. During auto provisioning, IP phones download
the common configuration file first, and then the MAC-oriented file. Therefore any
parameter in the MAC-oriented configuration file will override the same one in the
common configuration file.
Yealink supplies configuration files for each phone model, which is delivered with the
phone firmware. The configuration files, supplied with each firmware release, must be
used with that release. Otherwise, configurations may not take effect, and the IP phone
will behave without exception. Before you configure parameters in the configuration
files, Yealink recommends that you create new configuration files containing only those
parameters that require changes.
To deploy IP phones from the provisioning server:
1. Create per-phone configuration files by performing the following steps:
a) Obtain a list of phone MAC addresses (the bar code label on the back of the IP
phone or on the outside of the box).
b) Create per-phone <MAC>.cfg files by using the MAC-Oriented CFG file from
the distribution as templates.
c) Edit the parameters in the file as desired.
2. Create new common configuration files by performing the following steps:
a) Create <y0000000000xx>.cfg files by using the Common CFG file from the
distribution as templates.
b) Edit the parameters in the file as desired.
3. Copy configuration files to the home directory of the provisioning server.
4. Reboot IP phones to trigger the auto provisioning process.
IP phones discover the provisioning server address, and then download the
configuration files from the provisioning server.
For more information on configuration files, refer to Configuration Files on page 48 . For
protecting against unauthorized access, you can encrypt configuration files. For more
information on encrypting configuration files, refer to
Encrypting Configuration Files on
page 866 .
During the auto provisioning process, the IP phone supports the following methods to
discover the provisioning server address:

Zero Touch: Zero Touch feature guides you to configure network settings and the
provisioning server address via phone user interface after startup.

PnP: PnP feature allows IP phones to discover the provisioning server address by
broadcasting the PnP SUBSCRIBE message during startup.

DHCP: DHCP option can be used to provide the address or URL of the provisioning
