ENCRYPTION

(Country specific)

Off

. The system will not send or receive encrypted data.

On

. The system will only send and receive encrypted data. The call will not be

established if not all participants support encryption.

Auto

. The system will try to set up calls using encryption.

Point to point calls:

If the far end system supports encryption (AES or DES),

the call will be encrypted. If not, the call will proceed without encryption.

MultiSite calls*:

In order to have encrypted MultiSite calls, 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. The ‘closed padlock’ will
only be displayed on each site when all links in the MultiSite conference are
encrypted.

See

Icons

for a presentation of the icons.

Technical encryption information like encryption algorithm and encryption check
code used can be found in the

Call Status

menu.

* Only available on systems with MultiSite option supported and installed.


ENCRYPTION MODE
Auto

. The system will try to use the most secure encryption – AES – depending

on the capabilities of the other sites. For sites that fail to support AES encryp-
tion, DES encryption will be tried.

DES

. The system will try to set up the call using DES with 56 bits encryption. If

none of the other sites do support DES, no other type of encryption will be initi-
ated.

AES

. The system will try to use AES with 128 bits encryption when setting up

calls. If AES is not supported by the other site(s), no other type of encryption will
be initiated.
Both AES and DES encrypted sites can be connected at the same time.
