Chapter 3
Configuring the Cisco ATA for H.323
For an example of how to configure parameters for the TFTP Server configuration method, see the
"Creating Unique and Common Cisco ATA Configuration Files" section on page
Creating Unique and Common Cisco ATA Configuration Files
If you have many Cisco ATAs to configure, a good approach is to create two configuration files:
•
•
The following procedure demonstrates the steps needed to create these configuration files.
Note
The parameters used in this section help illustrate the process of creating a unique Cisco ATA
configuration file, and do not include all required H.323 parameters in the examples. See
"Basic and Additional H.323 Services,"
and additional configurable features. Also, refer back to
steps.
Procedure
Step 1
Use the h323_example.txt file as a template for creating a text file of values that are common to one
group of Cisco ATAs. The h323_example.txt file is included in the software-release zip file and contains
all default values. This file is shown without its annotations in the
section on page
Copy the h323_example.txt file and save it with a meaningful name, such as common.txt.
Configure all common parameters by editing the text file as desired. For example, you might configure
Step 2
the following parameters:
UseTftp:1
DHCP:1
TFtpURL:10.10.10.1
The settings in this example indicate that a group of Cisco ATAs is using the TFTP server with an IP
address of 10.10.10.1 to obtain their configuration files. These Cisco ATAs will use a DHCP server to
obtain their own IP addresses but not to obtain the TFTP server IP address (because the TftpURL
parameter has a configured value).
Step 3
Save your changes.
OL-4804-01
One file that will contain only parameter values unique to a specific Cisco ATA.
One file for parameters that will be configured with values common to a group of Cisco ATAs. If
this file is updated, all Cisco ATA devices in this common group can obtain the new configuration
data in a batch-mode environment.
