Secure Conference Call Identification
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.
There are interactions, restrictions, and limitations that affect the security level of the conference call
depending on the security mode of the participants' phones and the availability of secure conference
bridges.

Protected Call Identification
A protected call is established when a user phone and the phone on the other end are configured for protected
calling. The other phone can be in the same Cisco IP network, or on a network outside the IP network. Protected
calls can only be made between two phones. Conference calls and other multiple-line calls are not supported.
Establishment of a protected call follows this process:
1
A user initiates the call from a protected phone (protected security mode).
2
The phone displays the icon (encrypted) on the phone screen. This icon indicates that the phone is
configured for secure (encrypted) calls, but this does not mean that the other connected phone is also
protected.
