
To clear the MAC-local CFG file, reset the IP phone to factory configuration settings by
navigating to the

menu via web user interface and clicking
Reset local setting
.
Configurations defined never be saved to the <MAC>-local.cfg file
Most configurations made by users via phone user interface and web user interface can be
saved to the <MAC>-local.cfg file, but some static settings will never be saved to the <MAC>-
local.cfg file. For more information, refer to
Appendix F: Static Settings on page 1037 .
You need to reset the phone configurations not saved in the <MAC>-local.cfg file separately.
For more information, refer to
Resetting Issues on page 995 .
By default, the MAC-local.cfg file will be stored on the IP phone. The IP phone can be
configured to upload this file to the provisioning server each time the file updates. For more
information, refer to the parameter “static.auto_provision.custom.sync” described in the section
Configuration Parameters on page 159 .
Custom CFG File
You can create some new CFG files (e.g., sip.cfg, account.cfg) containing any combination of
configuration parameters. This especially useful when you want to apply a set of features or
settings to a group of phones using the boot file.
For more information on how to create a new CFG file, refer to
Yealink SIP IP Phones Auto
Provisioning Guide_V81
.
Resource Files
When configuring some particular features, you may need to upload resource files to IP
phones. Resource files are optional, but if the particular feature is being employed, these files
are required.
If the resource file is to be used for all IP phones of the same model, the access URL of resource
file is best specified in the common CFG file. However, if you want to specify the desired phone
to use the resource file, the access URL of resource file should be specified in the MAC-
Oriented CFG file. During provisioning, the IP phones will request the resource files in addition
to the configuration files. For more information on the access URL of resource file, refer to the
corresponding section in this guide.
The followings show examples of resource files:

Language packs

Ring tones

Local contact file

Input method file
