Technical Description of TANDBERG Gateway with software version G2

which encrypts "the session keys". When the session are collected by the remote end, encryption of the audio, video and data channels can start.

The encryption will be established automatically when both endpoints in the conference supports encryption with automatic key generation (and the conference is set up for encryption mode of operation).

Encryption is supported for meetings up to 768 kbps and for the TANDBERG feature DuoVideo.

Note: For an encrypted call, the endpoints must support encryption (AES or DES).

If encryption is enabled, the TANDBERG Gateway accepts both AES and DES encryption.

If one of the sites does not support encryption, encryption on both sides is disabled.
