Uploading an IP phone custom file

Last Updated : Jun 10, 2026 |

About this task

Use this procedure to upload custom files, settings, firmware upgrade files, or site-specific files, such as custom screen saver images, wallpaper images, or ringtones, to the Utility Server. You can upload a single file or a .zip archive. The files are available just after uploading. The Utility Server overwrites existing files.

The Utility Server stores uploaded custom files in the /var/www/html/custom directory. However, the uploaded files are available from the /var/www/html directory through symbolic links.

Note:

The new script accessToCustomDir.sh has been added to misc folder to provide an access to utility server /var/www/html/custom directory. It will enable users to remove unwanted files or folders from /var/www/html/custom directory.

cdto misc
sudo ./accessToCustomDir.sh help

Using linux command:

sudo ./accessToCustomDir.sh ls, to list files from /var/www/html/custom directory

sudo ./accessToCustomDir.sh rm <filename>, to remove a single file

sudo ./accessToCustomDir.sh "rm <filename*>", to remove multiple files with wild char *

Example:

sudo ./accessToCustomDir.sh rm testfile.txt
sudo ./accessToCustomDir.sh "rm *.txt"
