IP Phone Administrator Guide
Aastra Web UI
An administrator can setup and configure the IP phone using the Aastra Web UI.
The Aastra Web UI supports Internet Explorer and Gecko engine-based browsers
like Firefox, Mozilla or Netscape.
HTTP/HTTPS Support
The Aastra Web UI supports both Hypertext Transfer Protocol (HTTP) and
Hypertext Transfer Protocol over Secure Socket Layer (HTTPS) client and server
protocols.
HTTP is the set of rules for transferring files (text, graphic images, sound,
video, and other multimedia files) over the Internet. When you open your
Web browser, you are indirectly making use of HTTP. HTTP is an
application protocol that runs on top of the TCP/IP suite of protocols (the
foundation protocols for the Internet).
HTTPS is a Web protocol that encrypts and decrypts user page requests as well as
the pages that are returned by the Web server. HTTPS uses Secure Socket Layer
(SSL) or Transport Layer Security (TLS) as a sublayer under its regular HTTP
application layering.
SSL is a commonly-used protocol for managing the
security of a message transmission on the Internet.
It uses a 40-bit key size
for the RC4 stream encryption algorithm, which is considered an adequate degree
of encryption for commercial exchange. TLS is a protocol that ensures privacy
between communicating applications and their users on the Internet. When a
server and client communicate, TLS ensures that no third party may eavesdrop or
tamper with any message. TLS is the successor to SSL.
Note: An Administrator can enable or disable the Aastra Web UI for a
single phone or all phones in a network. For more information about
enabling/disabling the Aastra Web UI, see “Enabling/Disabling the
Aastra Web UI” on page 2-16.
Note: HTTPS uses port 443 instead of HTTP port 80 in its interactions
with the TCP/IP lower layer. Both the HTTP and HTTPS port numbers
are configurable using the configuration files, the IP Phone UI, the Aastra
Web UI and DHCP Option 66. For more information about configuring
these ports, see Chapter 4, the section, “Configuring the Configuration
Server Protocol” on page 4-108.
