Length of Prime DH Number (ISDN Only)
The encryption protocol requires the simultaneous exchange of a prime number
and an AES private key between terminals.
For H.320 calls you can choose between two prime number lengths:
• High Security (length 1024 bits)
• Very High Security (length 1536 bits)
Note
For IP calls, the System always uses the High Security option with a 1024-bit length.
Most common video communication terminals normally use the High Security prime
number length and the 128-bit AES private key.
