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 the Cisco Unified Communications Manager
Security Guide.
To view the phone security mode, you can view the security profile in Cisco Unified Communications Manager.

Authenticated, Encrypted, and Protected Phone Calls
In an authenticated call, all devices participating in the establishment of the call are trusted devices, and
authenticated by Cisco Unified Communications Manager.
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.
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.
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 non-protected phone, the security tone does not play.
