configurations may have an impact on your phone use. You can export
configuration file to check the current configuration of the IP phone and troubleshoot if
necessary. You can also import configuration files for a quick and easy configuration.
Three types of configuration files can be exported to your local system:

config.bin

<mac>-all.cfg

<mac>-local.cfg
We recommend you to edit the exported CFG file instead of the BIN file to change the
phone’s current settings if your phone is running firmware version 73 or later. For more
information on configuration files,
refer to Configuration Files on page 48 .
The config.bin file is an encrypted file. For more information on config.bin file, contact
your Yealink reseller.
Procedure
Configuration changes can be performed using the configuration files or locally.
