Note:
If you have an S8300 installed in the Branch Gateway, you can alternatively upgrade IP phones
using the Communication Manager web pages.
Note:
An alternative tool, the Avaya Software Update Manager (4.0 or higher), is a GUI application
that greatly simplifies the IP phone upgrade process, avoiding the need to know the file names
of the necessary upgrade files for each IP phone type. For further information, see Avaya
Software Update Manager User Guide, 14-300168.
Note:
The IP address of the TFTP server is the PMI.

Administering the upgrade

When using supported IP phones with the Branch Gateway, the IP phones require the downloading
of the settings file and the upgrade scripts. These files are stored in the script banks in NVRAM and
are preserved in the event of a reset or power failure. There are two script banks.
In addition, each phone can have a booter application and a phone application. There are four
banks that can store up to two phone images (booter and phone application files) at any given time.
Since the image files are stored in RAM, a reset or power failure erases these files. The image files
are used only for upgrading the IP phone, so there is no need to store them permanently. However,
the scripts are used by the IP phones when they are reset, and are therefore stored in NVRAM. You
