Configuration Interface Methods
Configuration Interface Methods Using HTTPS via the Aastra Web UI
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.
Reference
For more information on configuring the HTTPS protocol, see Chapter 4,
“Network Configuration of the IP Phones” , the sections:
• “Configuring the Configuration Server Protocol” on page 4-13
• “HTTPS Client/Server Configuration” on page 4-24
Notes:
1. The private key and certificate generate outside the phone and embed
in the phone firmware for use by the HTTPS server during the SSL
handshake.
2. Using the configuration files, the IP phone UI, or the Aastra Web UI,
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
