About the general download process

The 9600 Series IP Deskphones download upgrade files, settings files, language files,
certificate files, and software files from a file server. All of the file types can be downloaded
either via HTTP or HTTPS except the software files, which can only be downloaded via HTTP.
Avaya recommends HTTPS for downloading the file types because it ensures the integrity of
the downloaded file by preventing "man in the middle" attacks. Further, once trusted certificates
are downloaded into the deskphone, HTTPS ensures that the file server itself will be
authenticated via a digital certificate. HTTPS is not used for software file downloads because
9600 Series IP Telephone software files are already digitally signed, so there is no need to incur
additional processing overhead while downloading these relatively large files.
Note:
The files in the Software Distribution Packages discussed in this chapter are

identical for file servers running HTTP and HTTPS. The generic term "file server"
refers to a server running either HTTP or HTTPS.
When shipped from the factory, 9600 Series IP Deskphones might not contain the latest
software. When the deskphone is first plugged in, it will attempt to contact a file server, and will
download new software if the software version available on the file server is different than the
version on the phone. For subsequent software upgrades, the call server provides the capability
to remotely reset the deskphone, which then initiates the same process for contacting a file
server.
The deskphone queries the file server, which transmits a 96x1Supgrade.txt file (SIP protocol) or
96x1Hupgrade.txt file (H.323 protocol) to the telephone based on the SIG parameter setting.
(Software versions prior to Release 6.0 use a 96xxupgrade.txt file, which is not
protocol-specific.) The upgrade file tells the deskphone which software files the deskphone
should use.
The 9600 Series IP Deskphone then downloads a 46xxsettings.txt file. The settings file contains
options you have administered for any or all of the IP Deskphones in your network. For more
information about the settings file, see
has been downloaded, any language or certificate files required by the settings will be
downloaded. Finally, any new software files will be downloaded, if necessary.
