Option	Description
Encryption	Encryption is a process of disguising information into
	“ciphertext,” or data that will be unintelligible to an
	unauthorized person attempting access to the
	media.
	In the WebCommander the behavior of the system
	at a conference and participant level is dependant
	on MCU system.cfg flag settings set in the MGC
	Manager.
	Encryption supports all types of audio and video
	conferences including ISDN and IP participants.
	The following guidelines apply to encryption:

•Encrypted can be enabled at the conference or participants level

•Endpoints must support both AES 128 encryption and DH 1024 key-exchange standards to encrypt and to join an encrypted conference

•Encrypted conferences with ISDN participants require the installation of MUX+ card on the MCU

•Encrypted conferences with IP participants require the installation of IP+ card on the MCU

•The encryption feature supports all conference types, including: Cascading, People and Content, Operator, Meeting Rooms, Entry Queues, and Ad Hoc conferences

•In a cascaded encrypted conference it is important that the Link between the conferences is encrypted
