Guidelines
Configuration Parameter = Valid Value
 Separate each configuration parameter and value with an equal
sign.
 Set only one configuration parameter per line.
 Put the configuration parameter and value on the same line, and
do not break the line.
 The [$MODEL] can be added to the front of configuration
parameter to specify the value for specific phone groups.
$MODEL represents the phone model. The valid phone models
are: VP59, T58, CP960, T54W, T54S, T53W, T53, T52S, T48G,
T48S, T46G, T46S, T42G, T42S, 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 updates model-specific configurations and those
model-unspecified configurations. The phone model name T21P_E2 is
applicable to T21P E2 and T21 E2 phones.
Editing MAC-Oriented CFG File
The MAC-Oriented CFG file is only effective for the specific phone. It uses the 12-digit MAC
address of the IP phone as the file name. For example, if the MAC address of the IP phone is
00156574B150, the MAC-Oriented CFG file has to be named as 00156574b150.cfg
(case-sensitive) respectively.
MAC-Oriented CFG file contains configuration parameters which are expected to be updated
per phone, such as the registration information.
