Secure Conference Call Identification

You can initiate a secure conference call and monitor the security level of participants. A secure conference
call is established by using this process:
1 A user initiates the conference from a secure phone.
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 and maintains the secure level for the conference.
4 The phone displays the security level of the conference call. A secure conference displays the secure icon
to the right of Conference on the phone screen.
Secure calling is supported between two phones. For protected phones, some features, such as conference
Note
calling, shared lines, and Extension Mobility, are not available when secure calling is configured.
The following table provides information about changes to conference security levels depending on the initiator
phone security level, the security levels of participants, and the availability of secure conference bridges.
