Call Security Interactions and Restrictions
Cisco Unified Communications Manager checks the phone security status when conferences are
established and changes the security indication for the conference or blocks the completion of the call
to maintain integrity and also security in the system.
Table 1-4 provides information about changes to
call security levels when using Barge.
