Configuring the Cisco ATA Using a TFTP Server
Procedure
Step 1 Make a copy of the sk_example.txt file and rename it atadefault.txt.
Step 2 Make the desired configuration changes by editing the atadefault.txt file, then save the file.
Step 3 Convert the atadefault.txt file to a binary file by running the cfgfmt.exe tool, which is bundled with the
Cisco ATA software.
Note
The syntax of the cfgfmt program follows:
Syntax
cfgfmt [Encryption options] -sccp -tptag.dat input-text-file output-binary-file
–
–
–
–
–
Example
cfgfmt -sccp -tptag.dat atadefault.txt atadefault
Store the binary configuration file in the TFTP server root directory, overwriting the atadefault.cfg file
Step 4
that came bundled with the release-software download.
During the boot-up process, the Cisco ATA will download the output file as its configuration file unless
it first finds a Cisco ATA-specific configuration file named for the MAC address of the Cisco ATA. (If
you want to create a MAC-address configuration file for a specific Cisco ATA, see the
Configuration File for a Specific Cisco ATA" section on page

If you wish to encrypt the binary file for security reasons, see the
cfgfmt Tool" section on page
the resulting binary file will be called atadefault.cfg.x; if not encrypted with the EncryptKeyEx
parameter the resulting binary file name will be atadefault.cfg.
Encryption options are described in the
page 3-13.
sccp is the protocol you are using, which you must specify so that the cfgfmt tool will include
only the applicable protocol in the converted output binary file.
The ptag.dat file, provided with the Cisco ATA software version you are running, is used by
cfgfmt.exe to format a text input representation of the parameter/value pairs to its output binary
representation. Be sure this file resides in the same directory from which you are running the
cfgfmt program.
input-text-file is the input text file representation of the Cisco ATA configuration file.
output-binary-file is the final output binary file that Cisco ATA uses as the TFTP
configuration file.
If you want to make configuration changes after boot up, repeat the process of creating or editing
the text file containing the desired parameters, then converting the text file to the binary file and
storing the binary file on the TFTP server. For the configuration changes to take effect, reset the
Cisco ATA. (See the "Resetting the Cisco ATA Using Cisco CallManager" section on
page 3-26.)
