Upgrading the Cisco ATA Signaling Image
This section describes two methods for upgrading the Cisco ATA software for the H.323 protocol:
Upgrading the Signaling Image from a TFTP Server, page 8-1—This is the Cisco-recommended
method for the H.323 protocol. This method is the most efficient method and requires only a
one-time configuration change.
Upgrading the Signaling Image Manually, page 8-2—This method can be used if you must manually
upgrade the image of one Cisco ATA. However, this method is not the recommended upgrade
method because it is not as simple as the TFTP method.
This section also describes procedures for verifying a successf ul image upgrade:
Confirming a Successful Signaling Image Upgrade, page 8-5—Procedures for using your Web
browser or the voice configuration menu are included.
Caution Do not unplug the Cisco ATA while the function button is blinking. Doing so can cause permanent
damage to the device. The function button blinks during an upgrade.
Note The term Cisco ATA is used throughout this manual to refer to both the Cisco ATA186 and the
Cisco ATA188, unless differences between the Cisco ATA186 and Cisco ATA188 are explicitly stated.

Upgrading the Signaling Image from a TFTP Server

You can configure the CiscoATA to automatically download the latest signaling image from the TFTP
server. You do this configuring the parameter upgradecode in your Cisco ATA configuration file. (You
also would use this procedure if you wanted to perform a cross-protocol signaling imag e upgrade.) For
more information about setting up the configuration file, see the “Creating Unique and Common
Cisco ATA Configuration Files” section on page3-8.
Syntax of upgradecode Parameter
upgradecode:3,0x301,0x0400,0x0200,tftp_server_ip ,69,image_id,image_file_name
Definitions
The hexadecimal values that precede the tftp_server_ip variable must always be the values shown
in the syntax.
tftp_server_ip is the TFTP server that contains the latest signaling image file.
