Avaya 1603 Guia Do Utilizador

The 1600 Series IP Telephones download script files and settings files from either an HTTP or 
HTTPS server. These telephones download the application files from the HTTP server. The 
HTTPS server applies only if the server supports Transport Layer Security (TLS) encryption. 

Note:

The script files, application 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 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 application file the telephone 
must use. The application file is the software that has the telephony functionality, and is easily 
updated for future enhancements. In a newly installed telephone, the application file might be 
missing. In a previously installed telephone, the application file might not be the proper one. In 
both cases, the telephone requests a download of the proper application file from the HTTP 
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 application file again.

After checking and loading the application file, the 1600 Series 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 1600 Series IP Telephones in your network. For more 
information about the settings file, see 

When shipped from the factory, the1600 Series IP Telephones might not contain sufficient 
software for registration and operation. When the telephone is first plugged in, a software 
download from an HTTP server starts to give the phone its proper functionality.

For software upgrade downloads, the call server provides the capability for a remote restart of 
the 1600 Series IP Telephone. As a result of restarting, 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 Value Edition 1600 IP Telephone 
Installation and Maintenance Guide covers upgrades to a previously installed telephone and
