Chapter 7: Telephone Software and Binary Files
General Download Process
The 9600 Series SIP IP Telephones download script files, binary files, and settings files from
either an HTTP or HTTPS server. The HTTPS server applies only if the server supports
Transport Layer Security (TLS) encryption.
Note:
Note: The script files, binary files, and settings files discussed in this chapter are
identical for HTTP and HTTPS servers. The generic term “file server” refers to
both “HTTP server” and “HTTPS server.”
The file downloading process is the same for both servers, except that when you use an HTTPS
server, a TLS server is contacted first. The telephone queries the file server, which transmits a
script file to the telephone. The script file tells the telephone which binary file the telephone must
use. The binary file is the software that has the telephony functionality, and is easily updated for
future enhancements. In a newly installed telephone, the binary file might be missing. In a
previously installed telephone, the binary file might not be the proper one. In both cases, the
telephone requests a download of the proper binary file from the file server. The file server
downloads the file and conducts some checks to ensure that the file was downloaded properly.
If the telephone determines it already has the proper file, the telephone proceeds to the next
step without downloading the binary file again.
After checking and loading the binary file, the 9600 Series SIP IP Telephone, if appropriate,
uses the script file to look for a settings file. The settings file contains options you have
administered for any or all of the IP Telephones in your network. For more information about the
settings file, see Contents of the Settings File
on page 70.
Software
As part of installation, a conversion from H.323 to SIP signaling protocol is done as described in
"Converting Software on 9600 Series IP Telephones" of the Avaya one-X™ Deskphone Edition
for 9600 Series SIP IP Telephones Installation and Maintenance Guide. When the telephone is
first plugged in, a software download from an HTTP or HTTPS server starts to give the phone its
proper functionality.
For software upgrades, SIP Enablement Services (SES) provides the capability for a remote
reboot of the 9600 Series SIP IP Telephones. As a result, the telephone automatically starts
reboot procedures. If new software is available on the server, the telephone downloads it as part
of the reboot process. The Avaya one-X™ Deskphone Edition for 9600 IP Telephones
Installation and Maintenance Guide covers upgrades to a previously installed telephone and
