Chapter 3 Configuring the Cisco ATA for MGCP
Configuring the Cisco ATA Using a TFTP Server
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 3-9.
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:
• 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.
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 MGCP parameters in the examples. See Chapter 4,
“Cisco ATA-Supported MGCP Services,” for complete listings and descriptions of required parameters
and additional configurable features. Also, refer back to Table 3-3 on page 3-6 for all main configuration
steps.
Procedure
Step 1 Use the mgcp_example.txt file as a template for creating a text file of values that are common to one
group of Cisco ATAs. The mgcp_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 “Configuration Text File Template”
section on page 5-2.
Copy the mgcp_example.txt file and save it with a meaningful name, such as common.txt.
Step 2 Configure all common parameters by editing the text file as desired. For example, you might configure
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.
