### Upgrade Script File

An upgrade script file 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 also points to the settings file.

You download a default upgrade script file, sometimes called the “script file,” from
http://www.avaya.com/support. This file allows the telephone to use default settings for customer-definable options. This file must reside in the same directory as the upgrade script file, and must be called 46xxsettings.txt.

NOTE: Avaya recommends that the settings file have the extension *.txt. The Avaya IP Telephones can operate without this file. You can also change these settings with DHCP or, in some cases, from the dialpad of the telephone.
