Chapter 7: Telephone Software and Binary Files
General Download Process
The Avaya Agent Deskphone 16CC downloads 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 Avaya Agent Deskphone 16CC 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 C
ontents of the Settings File on page 66.
Software
When shipped from the factory, an Avaya Agent Deskphone 16CC does not contain sufficient
software for registration and operation. 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 16CC. 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 Agent Deskphone 16CC Installation and Maintenance Guide covers upgrades to a
previously installed telephone and related information.
