ETTINGS NSTALLATION
The configuration menu will be displayed; here you can set the following parameters:
Enable Encryption:
If encryption is activated, the System will use encryption in either H.323 or
H.320. It is also possible to enable/disable the encryption from the toolbar:
select the padlock icon, and press
For IP calls:
If encryption has been activated, the data protection procedure is active from
-
the beginning of a videoconference.
Encryption is active from start (ISDN):
If this option is selected, the System executes the encryption procedure from
-
the beginning of the ISDN connection.
If this option is not selected, the ISDN connection starts in unencrypted mode.
-
Encryption can be activated later at any time during the connection. To do
this, select the yellow padlock on the status bar and press OK.
Unprotected calls
From this drop-down menu you can choose the policy the System will apply if the
remote terminal is not able to support protected calls.
• Disconnect – The System will not allow connection with a remote terminal
that does not support encryption, and therefore automatically disconnects.
• Ask Confirmation – During the session negotiation phase, the System will
ask you to confirm that you want to establish an unprotected call.
• Inform – The System will inform you that you are about to establish an
unprotected connection by displaying a visual warning message.
•
State – The System will notify you that you are about to establish an
unprotected call, and once the connection is established an open padlock symbol
will be displayed on the status bar.
Length of AES Key (ISDN only)
From this drop-down menu you can choose (for ISDN connections only) three
AES key lengths:
• 128 bits
•
192 bits
• 256 bits
• <Auto> (allows optimal choice according to the characteristics of the
terminals negotiating the videoconference session.)
Note
For an IP connection, the key length is always 128 bits.
