Secure Calls
Depending on how your system administrator has configured your phone system, your phone might support
placing and receiving secure calls. To determine if you can place secure calls, see your administrator.
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 receives and transmits 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:
◦
When end-to-end secure media is established through the Secure Real-Time Transfer Protocol
(SRTP) and the call status is secure, the phone plays the secure indication tone (three long beeps
with brief pauses).
◦
When end-to-end nonsecure media is established through the Real-Time Protocol (RTP) and the
call status is nonsecure, the phone plays the nonsecure indication tone (six short beeps with brief
pauses).
If the Play Secure Indication Tone option is disabled (False), no tone is played.
• 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, contact your system administrator.
