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.
Table 1-5 provides information about changes to conference security levels
depending on the initiator’s phone security level, the security levels of
participants, and the availability of secure conference bridges.
