ENTER .
The call hangs up.
Encrypting a Call
When your videoconference requires a high level of security, you can encrypt
your calls. Encryption scrambles a callÕs video and audio signals so they are
unintelligible without the key to decryption.
When you encrypt a call, all of the information you send to the people at the far-
end site is encrypted. For example, if you send a still snapshot of an image, the
snapshot is encrypted.
This section describes how to encrypt individual, dialed calls. If you want to
encrypt all of your dialed calls, or if you want to encrypt nondialed calls, see your
system administrator or the Concorde¥4500 AdministratorÕs Guide.
T I P If the voice-only participant ends the call, but the call does not
disconnect from your system, press
HANG UP.
F Y I F.Y.I. Depending on your system conÞguration, encryption may not be
available to you. If you canÕt use it,
Encrypt This Call wonÕt appear
on your Dialing Directory screen.
