Configuration Interface Methods

HTTPS is enabled by default on the IP phones. When you open a browser window 
and enter an IP address or host name for a phone using HTTP, a server redirection 
occurs which automatically converts an HTTP connection to an HTTPS 
connection. After the redirection, a “Security Alert” certificate window displays 
alerting the user that information exchanged with the phone cannot be viewed or 
changed by others. Accepting the certificate then forwards you to the phone’s Web 
UI.

For more information on configuring the HTTPS protocol, see

you can configure the following regarding HTTPS:

- Specify HTTPS security client method to use (TLS 1.0 or SSL 3.0)
- Enable or disable HTTP to HTTPS server redirect function
- HTTPS server blocking of XML HTTP POSTS to the phone
