Chapter 3 Managing Cisco SIP IP Phones

Upgrading the Cisco SIP IP Phone Firmware

Procedure

Step 1 Copy the binary file P0S3xxyy.bin (where xx is the version number and yy is the subversion number) from CCO to the root directory of the TFTP server.

Step 2 Using a text editor, open the configuration file and update the image version specified in the image_version variable. The version name in image_version variable should match the version name (without the .bin extension) of the latest firmware that you downloaded.

Step 3 Reset each phone.

The phone contacts the TFTP server and requests its configuration files. The phone compares the image defined in the file to the image that it has stored in Flash memory. If the phone determines that the image defined in the file differs from the image in Flash memory, it downloads the image defined in the configuration file (which is stored in the root directory on the TFTP server). Once the new image has been downloaded, the phone programs that image into Flash memory and then reboots.

Note If you do not define the image_version parameter in the default configuration file, only phones for which you have updated their phone-specific configuration file with the new image version and restarted will use the latest firmware image. All other phones will use the older version until their configuration files have been updated with the new image version.
