Security Profiles
All Cisco Unified IP Phones that support Cisco Unified Communications Manager use a security profile,
which defines whether the phone is nonsecure, authenticated, or encrypted. For information about configuring
the security profile and applying the profile to the phone, see Cisco Unified Communications Manager Security
Guide.
To view the phone security mode, look at the Security Mode setting in the Security Configuration menu.

Authenticated, Encrypted, and Protected 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. You can also determine if the connected phone is secure and protected if a security
tone plays at the beginning of the call.
In an authenticated call, all devices participating in the establishment of the call are trusted devices, and
authenticated by Cisco Unified Communications Manager. When an in-progress call 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 trusted devices, and
authenticated by Cisco Unified Communications Manager. In addition, call signaling and media streams are
encrypted. An encrypted call offers a high level of security, providing integrity and privacy to the call. When
an in-progress call is being encrypted, the call progress icon to the right of the call duration timer in the phone
LCD screen changes to this icon: .
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.
In a protected call, a security tone plays at the beginning of a call to indicate that the other connected
phone is also receiving and transmitting encrypted audio and video (if video is involved). If your call is
connected to a nonprotected phone, the security tone does not play.
