Chapter3 Configuring the Cisco ATA for H .323

Configuring the Cisco ATA Using a TFTP Server

Step 4 Use the example_uprofile.txt file again, this time as a template for creating a text file of values that are

specific to one CiscoATA. For example, you might configure the following parameters:

UserID:8530709

GkorProxy:192.168.1.1

Save this file of CiscoATA-specific parameters as:

ata<macaddress>.txt

where macaddress is the non-dotted hexadecimal version of the MAC address of the Cisco ATA you are

configuring. This non-dotted hexadecimal MAC address is labeled on the bottom of most Cisco ATAs

next to the word “MAC.” The file name must be exactly 15 characters long. (However, if this filename

is supplied by the DHCP server, the name can be as long as 31 characters and can be any name with

printable ASCII characters.)

If necessary, you can obtain the non-dotted hexadecimal MAC address by using the atapna me.exe

command. For information on using the atapname.exe command, see the “Using atapname.exe Tool to

Obtain MAC Address” section on page 3-10. That section includes an example of a dotted decimal MAC

address and its corresponding non-dotted hexadecimal address.

Note The ata<macaddress>.txt file should contain only those parameters whose values are different

from the file of common parameters. Parameter values in the ata<macaddress> configuration file

will overwrite any manually configured values (values configured through the web or voice

configuration menu) when the Cisco ATA powers up or refreshes.

Step 5 On the top line of the ata<macaddress>.txt file, add an include command to include the name of the

common-parameters file, and save the file.

include:common.txt

UserID:8530709

GkorProxy:192.168.1.1

Step 6 Run the cfgfmt.exe tool, which is bundled with the CiscoATA software, on the ata<macaddress>.txt text

file to generate the binary configuration file. If you wish to encrypt the binary file for security reasons,

see the “Using the EncryptKey Parameter and cfgfmt Tool” section on page 3-11.

The syntax of the cfgfmt program follows:

Syntax

cfgfmt [-eRC4Password] -tpTagFile input-text-file outpu t-binary-file

–

-eRC4Password is the optional RC 4key to encrypt the binary TFTP file provided by the

cfgfmt program (up to eight alphanumeric characters).

–

pTagFile is the command used to specify the ptag.dat file that is provided with the

Cisco ATA software version you are running. Search on the keyword ptag to find the complete

name of the ptag file that is included with the Cisco ATA software for the signaling protocol

you are using. Be sure this file resides in the same directory from which you are running the

cfgfmt program. The ptag.dat file is used by cfgfmt.exe to format a text input representation of

the parameter/value pairs to its output binary representation.input-text-file is the input

text file representation of the Cisco ATA configuration file.

–

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 CiscoATA uses as the TFTP

configuration file.
