Secure calls
Depending on how your system administrator configured your phone system, your phone may support making
and receiving 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:
•
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 plays.
Nonprotected call
The phone does not have a Protected Device status in Cisco Unified Communications Manager. No
secure or nonsecure indication tone is played.
