MAC-Oriented Boot File
MAC-Oriented boot file, named <MAC>.boot. It will only be effective for a specific IP phone. In this way, you have
high permission to control each phone by making changes on a per-phone basis.
You can create a MAC-Oriented boot file for each phone by making a copy and renaming the boot template file
(y000000000000.boot). For example, if your phone MAC address is 00156574B150, rename the template file as
00156574b150.boot (lowercase).
Tip: MAC address, a unique 12-digit serial number is assigned to each phone. You can obtain it from the bar code on the
back of the phone.
Boot File Attributes
The following table lists the attributes you need to know in the boot template file.
Attributes
Description
#!version:1.0.0.1 It must be placed in the first line. Do not edit and delete.
include:config <xxx.cfg>
include:config "xxx.cfg"
Each “include” statement can specify a location of a configuration file. The con-
figuration file format must be *.cfg.
The locations in the angle brackets or double quotation marks support two
forms:
l Relative path (relative to the boot file):
For example, sip.cfg, HTTP Directory/sip.cfg
l Absolute path (or URL):
For example, http://10.2.5.258/HTTP Directory/sip.cfg
The location must point to a specific CFG file.
[$MODEL]
The [$MODEL] can be added to specify settings for specific phone models.
$MODEL represents the phone model name.
The valid phone model names are T57W, T54W, T53W, T53, T48U, T48S, T48G,
T46U, T46S, T46G, T43U, T42U, T42S, T42G, T41P, T41S, T40P, T40G, T29G,
T27G, T23P, T23G, T21P_E2, T19P_E2, and CP920.
Multiple phone models are separated by commas. For example, [T46S, T23G].
Note: The phone model name T21P_E2 is applicable to T21P E2 and T21 E2
phones.
overwrite_mode
Enable or disable the overwrite mode.
1-(Enabled) - If the value of a parameter in configuration files is left blank, or if a
non-static parameter in configuration files is deleted or commented out, the fact-
ory default value takes effect.
0-(Disabled) - If the value of a parameter in configuration files is left blank,
deleted or commented out, the pre-configured value is kept.
Note: Overwrite mode can only be used in boot files. If a boot file is used but
“overwrite_mode” is not configured, the overwrite mode is enabled by default.
static.specific_model.excluded_
mode
Enable or disable the exclude mode. The exclude mode applies to the con-
figuration files specified in the boot file.
0-Disabled (Append Mode), the phone downloads its own model-specific con-
figuration files and downloads other model-unspecified configuration files.
1-Enabled (Exclude Mode), the phone attempts to download its own model-spe-
cific configuration files; if there are no own model-specific configuration files
found on the server, it downloads model-unspecified configuration files.
