* Optional feature
Encryption (Secure Conference)*
Auto The system will try to set up calls using encryption.
Point to point calls: If the far end system supports encryption, the call will be encrypted. If not, the
call will proceed without encryption.
ISDN MultiSite calls: In order to have encrypted MultiSite calls on ISDN, all sites must support
encryption. The padlock symbol will indicate encryption mode (AES* or DES).If there is a mix of
AES* and DES encryption, only the symbol for DES encryption (single padlock) will be displayed.
IP MultiSite calls: Sites supporting encryption will be encrypted and sites not supporting encryption
will not be encrypted. The padlock symbol will be shown on the MultiSite if all sites support
encryption. The padlock symbol will be shown on the site connected to the MultiSite if this
connection to the MultiSite is encrypted.
If the far end supports encryption, the systems will initiate encryption after the call is connected (an
‘open padlock’ symbol will be displayed). When encryption has been established, a ‘closed padlock’
symbol will be displayed.
Off The system will not send or receive encrypted data.
Technical encryption information like encryption algorithm and encryption check code can be found in the ‘Call
Status’ menu.
Encryption Mode
Auto The system will try to use the most secure encryption - AES*, dependent on the capabilities of the
other sites. If AES* encryption is not supported by all the other sites, DES encryption will be tried.
AES* The system will try to use AES* with 128 bits encryption when setting up ISDN or IP calls. If AES* is
not supported by all other sites, no other type of encryption will be initiated.
DES The system will always try to set up the call using DES with 56 bits encryption on ISDN and IP. If
DES is not supported by all other sites, no other type of encryption will be initiated.
THE MULTISITE CAN RUN 4 ENCRYPTED SITES AT 128 KBPS AND 3 ENCRYPTED SITES AT 256KBPS.
TIP
BOTH AES* AND DES ENCRYPTION IS SUPPORTED FOR MIXED ISDN/IP CALLS. IN ADDITION AES* -AND DES ENCRYPTED SITES CAN BE
CONNECTED AT THE SAME TIME.
