Identifying Encrypted and Authenticated Phone Calls
When security is implemented for a phone, you can identify authenticated or encrypted phone calls by
icons on the screen on the phone.
In an authenticated call, all devices participating in the establishment of the call are authenticated by the
Cisco Unified Communications Manager. When a call in progress is authenticated, the call progress icon
to the right of the call duration timer in the phone LCD screen changes to this icon
In an encrypted call, all devices participating in the establishment of the call are authenticated by the
Cisco Unified Communications Manager. In addition, call signaling and media streams are encrypted.
An encrypted call offers the highest level of security, providing integrity and privacy to the call. When
a call in progress is being encrypted, the call progress icon to the right of the call duration timer in the
phone LCD screen changes to the following icon:
Note
If the call is routed through non-IP call legs, for example, PSTN, the call may be nonsecure even though
it is encrypted within the IP network and has a lock icon associated with it.

A user initiates the conference from a secure phone (encrypted or authenticated security mode).
Cisco Unified Communications Manager assigns a secure conference bridge to the call.
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.
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
