All Cisco Unified IP Phones that support Cisco Unified CallManager 5.1 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, refer to Cisco Unified CallManager Security Guide,
Release 5.1(1).
To view the security mode that is set for the phone, look at the Security Mode
setting in the Security Configuration menu. For more information, see the

When security is implemented for a phone, you can identify authenticated or
encrypted phone calls by icons on the screen on the phone.

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 CallManager. 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:
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.
