Information About Configuration Files
Configuration files reside in a TFTP server subdirectory (you specify the location of this subdirectory
with the tftp_cfg_dir parameter). For more information, refer to the
Firmware Upgrade
Be sure to customize configuration files before you power up the phone. When powered up, the phone
Note
automatically loads parameters stored in flash memory and then requests configuration files from the
TFTP server.
When modifying parameters, remember the following:

Upon startup, the phone attempts to download both configuration files. If neither file exists,
Note
a TFTP timeout occurs after approximately 9 seconds per file. If the files exist, they are
parsed and processed. These files are not required for the phone to initialize; however, it
takes longer (approximately 20 seconds) for the phone to boot because it is waiting for the
timeout on the TFTP server. Both configuration files can use the same values, or they can
contain empty values. If the files contain empty values, the phone boots using default values
for some of the parameters.
Values in the phone-specific configuration file take precedence over those in the default

Matrix.
Parameters in the configuration file override those stored in the phone's flash memory.
Locally changed parameters are used until the next reboot.
The name of each phone-specific configuration file is unique and is based on the MAC address of
the phone.
The format of the filename must be SIPXXXXYYYYZZZZ.cnf, where XXXXYYYYZZZZ is the MAC
address of the phone. The MAC address must be in uppercase; the .cnf extension must be in
lowercase (for example, SIP00503EFFD842.cnf).
You can find the MAC address of a phone on the middle sticker adhered to the base of the
Note
phone. You can also view it on the Network Configuration menu.
Each line in a configuration file must use the following format and must adhere to the following
rules:
variable-name : value ; optional comments
– Associate only one value with one variable.
Separate variable names and values with colons.
–
– Set only one variable per line.
Indicate the end of a line with <lf> or <cr><lf>.
–
Put the variable and value on the same line, and do not break the line.
