When a strictly confidential communication is required, the communication
system enables a connection with encrypted video and audio. A connection
conducted using this feature is known as an encrypted connection.
This chapter describes how to conduct an encrypted connection.
The Communication System is equipped with standard encryption, which
complies with the H.233, H.234 and H.235 standerdized by the ITU-T.
Streaming and recording are not available during an encrypted connection.
