Description
found on the server, it downloads model-unspecified configuration files.
Note: Exclude mode can only be used in boot files. If a boot file is used but “stat-
ic.specific_model.excluded_mode” is not configured, the exclude mode is dis-
abled by default.
Tip: The line beginning with “#” is considered to be a comment. You can use “#” to make any comment on the boot file.
Customizing a Boot File
Procedure
1.
Open a boot template file.
2.
To add a configuration file, add include:config < > or include:config “” to the file. Each starts on a separate line.
3.
Specify a configuration file for downloading.
For example:
include:config <configure/sip.cfg >
include:config “http://10.2.5.206/configure/account.cfg”
include:config “http://10.2.5.206/configure/dialplan.cfg”
4.
To specify configuration files for specific phone models, add specific phone models in front of include:config < >
or include:config “”. Multiple phone model names are separated by commas.
For example:
[T46S, T48S]include:config <configure/sip.cfg >
[T23G]include:config “http://10.2.5.206/configure/account.cfg”
## file sip.cfg only applies to T46S and T48S phones, file account.cfg only applies to T23G phones
5.
Specify the overwrite mode and exclude mode.
For example:
overwrite_mode = 1
static.specific_model.excluded_mode = 1
6.
Save the boot file and place it on the provisioning server.

Configuration Files
Yealink supports two configuration template files: Common CFG file and MAC-Oriented CFG file.
These configuration files contain two kinds of parameters:
l Static: The parameters start with a prefix “static.”, for example, static.auto_provision.custom.protect.
l Non-static: The parameters do not start with a prefix “static.”, for example, local_time.date_format.
You can deploy and maintain a mass of Yealink phones automatically through configuration files stored in a pro-
visioning server.
Note: For protecting against unauthorized access, you can encrypt configuration files. For more information on encrypting
configuration files, refer to Encrypting and Decrypting Files.
