Security Restrictions - Cisco Cius Overview

Overview of Cisco Cius

Security Restrictions

A user cannot barge in to an encrypted call if the Cisco Cius device that is used to barge is not configured for
encryption. When barge fails in this case, a fast busy tone plays on the Cisco Cius on which the user initiated
the barge.
If the initiator Cisco Cius device is configured for encryption, the barge initiator can barge in to a nonsecure
call from the encrypted Cisco Cius device. After the barge occurs, Cisco Unified Communications Manager
classifies the call as nonsecure.
If the initiating Cisco Cius is configured for encryption, the barge initiator can barge in to an encrypted call,
and Cisco Cius indicates that the call is encrypted.

After you set up the IP telephony system and configure system-wide features in Cisco Unified Communications
Manager, you can add Cisco Cius to the system.
The following topics provide an overview of procedures for adding Cisco Cius to your network:
