Understanding Security Features for Cisco Unified IP Phones
Establishing and Identifying Secure Conference Calls
You can initiate a secure conference call and monitor the security level of participants. A secure
conference call is established using this process:
1. A user initiates the conference from a secure phone (encrypted or authenticated security mode).
2. Cisco Unified Communications Manager assigns a secure conference bridge to the call.
3. As participants are added, Cisco Unified Communications Manager verifies the security mode of
each phone (encrypted or authenticated) and maintains the secure level for the conference.
4. The phone displays the security level of the conference call. A secure conference displays
(encrypted) or (authenticated) icon to the right of “Conference” on the phone screen. If icon
displays, the conference is not secure.
Note There are interactions, restrictions, and limitations that affect the security level of the conference call
depending on the security mode of the participant’s phones and the availability of secure conference
bridges. See Table 1-4 and Table 1-5 for information about these interactions.
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.
