• Protected call—The phone is a secure (encrypted and trusted) device on the Unified CM server and
is configured as a "Protected Device" in Unified CM Administration.
If "Play Secure Indication Tone" is enabled (True) in Unified CM 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). (This capability is a change with this release.)
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 Unified CM. No
secure or nonsecure indication tone is played.
• Non-secure call—The phone is not protected on the Unified CM server and the call status is
nonsecure.
For more information, see your system administrator.
