Secure Calls
Your phone can support these types of calls:
• Authenticated call—The identities of the phones participating in the call have been verified.
• Encrypted call—The phone is receiving and transmitting encrypted audio (your conversation) within
the Cisco Unified Communications Manager network. Encrypted calls are authenticated.
• Protected call—The phone is a secure (encrypted and trusted) device on the Cisco Unified
Communications Manager server and is configured as a "Protected Device" in Cisco Unified
Communications Manager Administration.
If "Play Secure Indication Tone" is enabled (True) in Cisco Unified Communications Manager
Administration, the protected phone plays a secure or nonsecure indication tone at the beginning of the
call:
• Nonprotected call—The phone does not have a "Protected Device" status in Cisco Unified
Communications Manager. No secure or nonsecure indication tone is played.
• Nonsecure call—The phone is not protected on the Cisco Unified Communications Manager server and
the call status is nonsecure.
For more information, see your system administrator.
