The system will try to use the most secure encryption - AES, dependent on the
capabilities of the other sites. For sites that do not support AES encryption, DES
encryption will be tried.
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.
DES
The system will always try to set up the call using DES with 56 bits encryption on
ISDN and IP. If all other sites do not support DES, no other type of encryption will be
initiated.
Both AES and DES Encryption are supported for mixed ISDN/IP calls. In addition AES -and DES
Encrypted sites can be connected at the same time.
