Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide for MGCP (version 3.0)
OL-4803-01
Chapter 3 Configuring the Cisco ATA for MGCP
Configuring the Cisco ATA Using a TFTP Server
Example
cfgfmt -mgcp -tptag.dat ata0a141e28323c.txt ata0a141e28323c
This example is based on a Cisco ATA MAC address of 10.20.30.40.50.60, which converts to the
two-digit, lower-case hexadecimal representation of each integer as 0a141e28323c.
When you convert the ata<macaddress>.txt file to a binary file, the binary file will merge the two text
files to form one Cisco ATA-specific binary configuration file for your Cisco ATA.
If the same parameter is configured with different values in these two files, the value in the
ata<macaddress>.txt file takes precedence over the value in the common.txt file.
Step 7 Store all binary configuration file(s) in the TFTP server root directory. For information about possible
configuration file names, see the “Configuration Files that the cfgfmt Tool Creates” section on
page 3-13.
When the Cisco ATA powers up, it will retrieve its configuration file(s) from the TFTP server.
Step 8 If you want to make configuration changes after boot up, repeat the process of creating or editing the
text files containing the desired parameters, then converting the ata<macaddress>.txt text file to the
binary file(s) and storing the binary file(s) on the TFTP server. For the configuration changes to take
effect immediately, refresh the Cisco ATA. (See the “Refreshing or Resetting the Cisco ATA” section
on page 3-25.)
After being refreshed, the Cisco ATA will download the updated ata<macaddress> configuration file(s).
Note If you do not perform a refresh procedure, the Cisco ATA will update its configuration the next
time it contacts the TFTP server, which is based on the configured value of the CfgInterval
parameter.
Using atapname.exe Tool to Obtain MAC Address
This bundled tool is useful for converting the dotted decimal version of the Cisco ATA MAC address
(available on the Cisco ATA Web configuration page or from the voice configuration menu code 24#) to
its default Cisco ATA profile name. This name has the following format:
ataxxxxxxxxxxxx
where each xx is the two-digit, lower-case hexadecimal representation of each integer in the dotted,
decimal version of the Cisco ATA MAC address. This is the name you use for the unique Cisco ATA
binary configuration file.
