Two configuration files on the file server are important to understand. Other files are needed when the Avaya IP Telephones need an upgrade. The important files are:

- An upgrade script file, which tells the IP telephone whether the telephone needs to upgrade software. The Avaya IP Telephones attempt to read this file whenever they reset. The upgrade script file is also used to point to the settings file.
- The settings file contains the option settings that enable, disable, or otherwise customize the settings you might need to tailor the Avaya IP Telephones for your enterprise.

NOTE: You can use one settings file for all your Avaya IP Telephones including the 9600 Series IP Telephones covered in this document, and 4600 Series IP Telephones, as covered in the 4600 Series IP Telephone LAN Administrator Guide (Document 555-233-507).

In addition to the upgrade script and settings files, you need the latest binary code used in the Avaya IP Telephones.
