Description
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: T54S, T52S, T48S, T48G, T46S, T46G,
T42S, T42G, T41P, T41S, T40P, T40G, T29G, T27P, T27G, T23P, T23G,
T21P E2, T21 E2, T19P E2 and T19 E2.
Multiple phone models are separated by commas. For example, [T46S,
T23G].
overwrite_mode
Enable or disable the overwrite mode. The overwrite mode applies to
the configuration files specified in the boot file. Note that it only
affects the parameters pre-provisioned via central provisioning.
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 factory 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 the value of the parameter “overwrite_mode” is not
configured, the overwrite mode is enabled by default.
specific_model.excluded_m
ode
Enable or disable the exclude mode. The exclude mode applies to the
configuration files specified in the boot file.
0-Disabled (Append Mode), the phone downloads its own
model-specific configuration files, and downloads other
model-unspecified configuration files.
1-Enabled (Exclude Mode), the phone attempts to download its own
model-specific configuration files; if there is no own model-specific
configuration files 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 the value of the parameter “specific_model.excluded_mode” is not
configured, the exclude mode is disabled by default.
Tip
The line beginning with “#” is considered to be a comment. You can use “#” to make any comment in the
boot file.
