Phone Call Security
When security is implemented for a phone, you can identify secure phone calls by icons on the phone screen.
You can also determine whether the connected phone is secure and protected if a security tone plays at the
beginning of the call.
In a secure call, all call signaling and media streams are encrypted. A secure call offers a high level of security,
providing integrity and privacy to the call. When a call in progress is encrypted, the call progress icon to the
right of the call duration timer in the phone 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
Note
it is encrypted within the IP network and has a lock icon associated with it.
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 secure audio. If your call connects to a nonsecure phone, the security tone
does not play.
Note Secure calling is supported between two phones. Secure conference, Cisco Extension Mobility, and shared
lines can be configured by secure conference bridge.
When a phone is configured as secure (encrypted and trusted) in Cisco Unified Communications Manager, it
can be given a "protected" status. After that, if desired, the protected phone can be configured to play an
indication tone at the beginning of a call:
• Protected Device: To change the status of a secure phone to protected, check the Protected Device check
box in the Phone Configuration window in Cisco Unified Communications Manager Administration
(Device > Phone).
• Play Secure Indication Tone: To enable the protected phone to play a secure or nonsecure indication
tone, set the Play Secure Indication Tone setting to True. By default, Play Secure Indication Tone is set
to False. You set this option in Cisco Unified Communications Manager Administration (System >
Service Parameters). Select the server and then the Unified Communications Manager service. In the
