Chapter 3 Configuring the Cisco ATA for MGCP
Steps Needed to Configure the Cisco ATA
Table 3-3 Basic Steps to Configure the Cisco ATA in a TFTP Environment
Action Reference
1. Download the desired Cisco ATA release software zip file from
the Cisco web site and store it on the TFTP server.
Setting Up the TFTP Server with Cisco ATA
Software, page 3-8
2. Follow these basic steps to create a unique Cisco ATA
configuration file, which actually entails creating two files:
a. Create a Cisco ATA configuration text file that contains
parameters that are common to all Cisco ATAs in your
network.
b. Create a unique Cisco ATA configuration text file that
contains parameters that are specific to a Cisco ATA.
Make sure to use an include command in the unique
configuration file to pull in values from the common
configuration file.
c. Convert the unique configuration file to binary format.
d. Place the unique binary configuration file on the TFTP server.

Configuration Files, page 3-9
3. Optionally, create a default configuration file called
atadefault.cfg, which the Cisco ATA will download from the
TFTP server only if the unique Cisco ATA file called
ata<macaddress> (with a possible file extension) does not exist
on the TFTP server. For information about possible configuration
file names, see the “Configuration Files that the cfgfmt Tool
Creates” section on page 3-13.

4. Configure the upgradecode parameter so that the Cisco ATA will
obtain the correct signaling image from the TFTP server when the
Cisco ATA powers up.

page 7-1
5. Configure the desired interval for the Cisco ATA to contact the
TFTP server to check for a configuration-file update or an
upgrade of the signaling image file.
Configuring Refresh Interval, page 4-2
6. Configure the method with which the Cisco ATA will locate the
TFTP server at boot up time.
Configuring the Cisco ATA to Obtain its
Configuration File from the TFTP Server, page 3-18
7. Power up the Cisco ATA.
8. If you make configuration changes to the Cisco ATA or upgrade
the signaling image on the TFTP server, you can refresh the
Cisco ATA so that these changes take effect immediately.
Otherwise, these changes will take effect when the specified
interval (CfgInterval parameter value) for the TFTP query
expires.
