The 9600 Series IP Telephones can download script files, application files, and settings files from either an HTTP or HTTPS server. The telephone queries the file server, which transmits a script file to the telephone. This script file, at a minimum, tells the telephone which application file the telephone must use. The application file is the software that has the telephony functionality.
The telephone uses the script file to determine if it has the proper application file. If the telephone determines the proper application file is missing, the telephone requests an application file download from the file server. The file server then downloads the file and conducts some checks to ensure that the file was downloaded properly. If the telephone determines it already has the proper file, the telephone proceeds as described in the next paragraph without downloading the application file again.
The telephone checks and loads the application file, then uses the script file to look for a settings file, if appropriate. The optional settings file can contain settings you have administered for any or all of the 9600 Series IP Telephones in your network. For more information about this download process and settings file, see Chapter 6: Telephone Software and Application Files.
