Common CFG File
Common CFG file, named <y0000000000xx>.cfg, contains parameters that affect the basic operation of the IP
phone, such as language and volume. It will be effective for all phones in the same model. The common CFG file
has a fixed name for each phone model.
The following table lists the name of the common CFG file for each phone model:
Phone Model Common CFG file
T57W y000000000097.cfg
T54W y000000000096.cfg
T53W/T53 y000000000095.cfg

MAC-Oriented CFG File
MAC-Oriented CFG file, which is named after the MAC address of the IP phone. For example, if the MAC address of
an IP phone is 00156574B150, the name of MAC-Oriented CFG file is 00156574b150.cfg (lowercase). It contains
parameters unique to a particular phone, such as account registration. It will only be effective for a MAC-specific IP
phone.
