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

are authenticated by 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

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.
