MAC-Oriented CFG file
A MAC-Oriented CFG file contains parameters unique to a particular phone. It will only
be effectual for a specific IP phone. The MAC-Oriented CFG file is named after the MAC
address of the IP phone. For example, if the MAC address of an IP phone is
00156574B150, the name of the MAC-Oriented CFG file must be 00156574b150.cfg
(case-sensitive).
MAC-local CFG file
A MAC-local CFG file contains changes that users make via web user interface and
phone user interface. It will only be effectual for a specific IP phone. The MAC-local CFG
file is named after the MAC address of the IP phone. This file is stored locally on the IP
phone and can also be uploaded to the provisioning server.
The MAC-local CFG file enables the phone to protect personalized settings. For more
information on how to protect personalized settings, refer to the section
Specific
Scenarios-Protect Personalized Settings
in Yealink IP Phones Auto Provisioning Guide,

Central Provisioning
IP phones can be centrally provisioned from a provisioning server using the
configuration files (<y0000000000xx>.cfg and <MAC>.cfg). You can use a text-based
editing application to edit configuration files, and then store configuration files to a
provisioning server. For more information on the provisioning server, refer to Provisioning
Server on page 28.
IP phones can obtain the provisioning server address during startup. Then IP phones
download configuration files from the provisioning server, resolve and update the
configurations written in configuration files. This entire process is called auto
provisioning. For more information on auto provisioning, refer to Yealink IP Phones Auto
Provisioning Guide, available online:
http://www.yealink.com/DocumentDownload.aspx?CateId=142&flag=142.
When modifying parameters, learn the following:
Parameters in configuration files override those stored in the IP phone’s flash
memory by default.
The .cfg extension of configuration files must be in lowercase.
Each line in a configuration file must use the following format and adhere to the
following rules:
variable-name = value
- Associate only one value with one variable.
- Separate each variable name and value with an equal sign.
