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.
