NOTE
Encryption
The gateway will allow DES and AES 128 encrypted
conferences to take place. Encryption can operate in two
modes.
When set to Transparent, the Gateway will forward the encryption modes of the connected devices
transparently. The encryption modes seen on each side of the Gateway are similar. The gateway will only encrypt
calls if both sides support encryption. The settings for H.320 and H.323 doesn’t have any meaning in this mode.
When set to Independent, the Gateway will use the settings made for the H.320 (ISDN) and H.323 (IP) side. The
encryption modes on each side of the Gateway are independent of each other. One endpoint might show that the
call is encrypted will the other endpoint shows an unencrypted call.
On Encryption is required. Gateway connection is only established if encryption can be established on this
side.
Off No encryption. Gateway connection will be established without any encryption on this side.
Auto Use encryption if available. Gateway will try to establish an encrypted connection, the connection will be
established regardsless if encryption on this side is available.
A typical application of this feature is when an external crypto device is used on the ISDN interface. In this case
might an administrator want to set the Gateway’s encryption on the H.320 side to Off and on the H.323 side to
On.
H.264
Allows H.264 video capabilities to be transmitted through the gateway. When disabled no H.264 video capabilities
will be transmitted.
