Upgrading the H.323 Signaling Image
Note A refresh procedure will update the CiscoATA configuration file. A reset procedure will also update the
CiscoATA configuration file, and will additionally power-down and power-up the CiscoATA. A reset
should not be necessary if your only goal is to update the configu ration 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 CiscoATA, 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 CiscoATA 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 CiscoATA 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 CiscoATA, 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 CiscoATA and to obtain
software upgrades, you must manually upgrade to the latest signaling image immediate ly after the
Cisco ATA boots up. In this case, see the “Upgrading the Signaling Image Manually” section on
page 8-2.
