Chapter 3 Configuring the Cisco ATA for H.323
Upgrading the H.323 Signaling Image
Note A refresh procedure will update the Cisco ATA configuration file. A reset procedure will also update the
Cisco ATA configuration file, and will additionally power-down and power-up the Cisco ATA. A reset
should not be necessary if your only goal is to update the configuration file.
HTTP Procedure to Refresh the Cisco ATA
To refresh the Cisco ATA, enter the following command from your web browser:
http://<ipaddress>/refresh
where ipaddress is the IP address of the Cisco ATA that you are refreshing.
HTTP Procedure to Reset the Cisco ATA
To reset the Cisco ATA, enter the following command from your web browser:
http://<ipaddress>/reset
where ipaddress is the IP address of the Cisco ATA that you are resetting.
HTTP Refresh and Reset Access-Control Configuration
You can configure the Cisco ATA to disable the use of the http://ip/refresh command that forces a
configuration-file update. Use Bit 8 of the OpFlags parameter to control this refresh access.
You can also configure the Cisco ATA to disable the use of the http://ip/reset command that resets the
Cisco ATA. Use Bit 9 of the OpFlags parameter to control this reset access.

Upgrading the H.323 Signaling Image
For instructions on how to upgrade the Cisco ATA to the most recent H.323 signaling image, refer to the
following list:
To use the recommended TFTP method of upgrading the Cisco ATA, see the “Upgrading the
Signaling Image from a TFTP Server” section on page 8-1.
In the rare instance that you are not using the TFTP server to configure the Cisco ATA and to obtain
software upgrades, you must manually upgrade to the latest signaling image immediately after the
Cisco ATA boots up. In this case, see the “Upgrading the Signaling Image Manually” section on
page 8-2.
