can upgrade up to two types of phones and then release the banks for use with another IP phone
type.
There are cases where the image files are the same for different IP phone types. In these cases,
you can download the image files once for the IP phones that use the same image. The scripts are
global to all the supported IP phone images.
You can download and then upload setting script files in order to update their content. It is not
recommended to change the upgrade script.
By default, the RAM allocation for TFTP server is 10 MB. You can increase the RAM allocation for
TFTP server to up to 11.264 MB at the expense of the Sniffer cache application. The maximum
RAM for both applications is 12 MB.
There are four image banks, supporting two IP phone images in RAM, provided the combined file
sizes do not exceed the RAM allocation for TFTP server. The maximum size for a booter application
or phone application file is 4.5 MB. Thus, it is possible that in some cases, the allocation may only
suffice for one complete IP phone image and not two.
Caution:
To activate a change in RAM allocation to the TFTP server, reset is required. Upon reset, any
phone image files stored in RAM are erased.
Note:
Previous releases of TFTP server required the configuration of the DHCP server option 43/176
with the named value pair TFTPDIR=/phonedir/ in order to allow the IP phone to access the files
in this directory. This configuration is still supported but is no longer required.

IP phone upgrade files include script files, boot images files, and phone application image files. You
can download these files to a remote FTP/TFTP/SCP server, or you can download them to a laptop
and copy them to a USB device. You can then copy the upgrade files to the Branch Gateway.
Note:
The Branch Gateway uses the SSH protocol to support the use of SCP for secure file transfer.
When using SCP, the Branch Gateway is the SCP client, and an SCP server must be
configured on the management station. For more information about establishing an SCP
session, see Administration for the Avaya Branch Gateway G430, 03-603228.
1. Check the available memory size for the image files using the show application-
memory command. If the memory size needs to be changed, proceed to step 2 on
page 101, otherwise proceed to step
6 on page 100.
2. Set the memory size for the image files using the ip tftp-server file-system size
command.
