The phone firmware files are installed as part of the IP Office Manager application and are found in the application's installation directory. By default, the directory is found at c:\Program Files\Avaya\IP Office\Manager.

The same firmware files can also be obtained directly from the software package used to install IP Office Manager without having to perform the installation. The files are located in the \program files\Avaya\IPOffice\Manager sub-folder of the installation directory.

Note that these sets of files include .bin files that are also used for other devices including the IP Office system itself.
