Upgrading the Cisco ATA Signaling Image

This section describes two methods for upgrading the Cisco ATA software for the SIP protocol:

• Upgrading the Signaling Image from a TFTP Server,
• Upgrading the Signaling Image Manually,

Upgrading the Signaling Image from a TFTP Server

You can configure the Cisco ATA to automatically download the latest signaling image from the TFTP server. You do this configuring the parameter upgrade code in your Cisco ATA configuration file.

Process

Whenever the Cisco ATA administrator stores a new signaling image (denoted by a change to the image_id), the Cisco ATA upgrades its firmware with the new image_file. To contact the TFTP server, the Cisco ATA uses the TFTP server IP address that is contained within the value of the upgradecode parameter.

Upgrading the Signaling Image Manually

To perform the upgrade, follow these steps:

1. Run the executable file from the Microsoft Windows DOS or command prompt. You will receive instructions on how to upgrade.
2. On the Cisco ATA, press the function button to invoke the voice configuration menu.
3. Using the telephone keypad, enter the following:

100# ip_address_of_PC * port #

This is the IP address of the PC and the port number at the DOS prompt where you invoked the ata186us.exe file.
For example, if the IP address is 192.168.1.10, and the port number is 8000 (the default), then enter:

100#192*168*1*10*8000#

When the upgrade is complete, the "Upgrade Successful" prompt will sound.

Confirming a Successful Signaling Image Upgrade

You can verify that you have successfully upgraded the Cisco ATA signaling image by using one of the following methods:

• Using a Web Browser
• Using the Voice Configuration Menu

Using a Web Browser

1. Open your web browser.
2. Enter the IP address of your Cisco ATA Web configuration page: http://<IP address>/dev
3. Refresh the page to clear the cache. The image version number and its build date should appear at the bottom-left corner of the Cisco ATA Web configuration page.

Using the Voice Configuration Menu

To use the voice configuration menu to verify a successful image upgrade, perform the following steps:

1. Pick up the telephone handset attached to the Phone1 port of the Cisco ATA.
2. Press the function button on the Cisco ATA.
3. Press 123# on the telephone keypad to play out the image version number.
