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

Encrypted Phone Call Identification
When security is enabled for a phone, a lock icon is displayed on the phone screen during an encrypted call.
In a secure 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. If your call is connected to a non-protected phone, the security
tone does not play.
In a secure call, all call signalling and media streams are encrypted. An encrypted call offers a high level of
security, providing integrity and privacy to the call. When a call in progress is being encrypted, the call icon
on the phone screen changes to the lock 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.
Note Secured calling is supported for connections between two phones only. Some features, such as conference
calling, and Cisco Extension Mobility are not available when secured calling is configured.
