Chapter 7: Telephone Software and

Understanding the general download process

9600 Series IP Deskphones download upgrade files, settings files, language files, certificate files,
and software files from a file server. 9600 Series IP deskphone downloads all the file types either
through HTTP or HTTPS except the software files, which can only be downloaded through HTTP.
Avaya recommends HTTPS for downloading the non software file types because it ensures the
integrity of the downloaded file by preventing man in the middle attacks. Further, after the
deskphone downloads the trusted certificates, HTTPS ensures that the file server is authenticated
through a digital certificate. The deskphone does not use HTTPS for software file downloads
because 9600 Series IP deskphones software files are already digitally signed. You need not 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 you first plug in the 9600 Series IP deskphone, the phone attempts to contact a file server,
and downloads new software only if the software version available on the file server is different than
the version on the phone. For subsequent software upgrades, the call server can remotely reset the
phone, and the phone initiates the same process for contacting a file server.
The phone queries the file server, which, transmits a 96x1Supgrade.txt file (SIP protocol) or
96x1Hupgrade.txt file (H.323 protocol) to the deskphone based on the SIG parameter setting;
software versions before Release 6.0 use a 96xxupgrade.txt file, which is not protocol-specific. The
software files that the deskphone must use depend on the instructions in the upgrade file.
The 9600 Series IP deskphones then downloads a 46xxsettings.txt file. The settings file contains
options that you have administered for any or all the phones in your network. For more information
about the settings file, see
the phone downloads the language or the certificate files and then any new software files that the
settings require.
