Length of Prime DH Number Key (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 Codec 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.

2. Press the “Enable Licence” icon.

Possible options with licence keys, on different codecs:

a. ISDN connections up to 768Kbps

b. PRI

connections

c. NIC(X.21,V.35, RS.449, RS.530, RS.366) connections

d. G.703

connections

e. MCU

Video coding
Enable/disable H.264 coding
Channels

Determine if channels are to be bonded or not (ISDN only)

Note

With audio and video encoder/decoder settings set to <Auto> the codec choose the encoder/decoder based on the

connection bit rate.

DualVideo H.239 and DuoVideo

can also be enabled/disabled.
