Guidelines
The URL must point to a specific CFG file. The CFG files are
downloaded in the order listed (top to bottom). The parameters in
the new downloaded configuration files will override the duplicate
parameters in files downloaded earlier.
3) The “include” statement can be repeated as many times as
needed.
4) The [$MODEL] can be added to specify settings for specific phone
models. $MODEL represents the phone model name. The valid
phone model names are: VP59, T58, CP960, T54W, T54S, T53W,
T53, T52S, T48S, T48G, T46S, T46G, 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]. It is only applicable to IP phones (except
W53P/W60P/CP930W-Base) running firmware version 83 or later.
Note: The phone model name T21P_E2 is applicable to T21P E2 and
T21 E2 phones.
overwrite_mode
Enable or disable the overwrite mode. The overwrite mode is applied
to the configuration files specified to download. 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: This parameter 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_
mode
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. Exclude mode
feature is only applicable to IP phones (except
