Avaya 4600 Manual Do Utilizador

The Avaya 4600 IP Telephones can get useful application information from the TFTP server. 
The telephones also can upgrade themselves using files stored on the TFTP server. After 
downloading software, the Avaya 4600 Series IP Telephones can operate without a file server. 
However, some functionality can be lost if the file server is not available for a telephone reset.

HTTP is potentially a more secure alternative to TFTP, particularly when Transport Layer 
Security (TLS) is used to create HTTPS (Secure HTTP). You can store the same application 
software, script file, and settings file on an HTTP server as you can on the TFTP server. With 
proper administration, the telephone seeks out and uses that material appropriately. However, 
not all 4600 Series IP Telephones support HTTP, as indicated in 

As with TFTP, some functionality might be lost by a reset if the HTTP server is not available.

The Domain Name System (DNS) is a distributed Internet directory service. DNS is used mostly 
to translate between domain names and IP addresses. Release 1.5 and later Avaya IP 
Telephones can use DNS to resolve names into IP addresses. In DHCP, TFTP, and HTTP files, 
DNS names can be used wherever IP addresses were available as long as a valid DNS server 
is identified first. See 

on page 110.
