Description
When a phone is configured as secure (encrypted
and trusted) in Cisco Unified CM, 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.
Only protected phones hear these secure or
nonsecure indication tones. Nonprotected phones
never hear tones.
If the overall call status changes during the call, the
indication tone changes accordingly. At that time,
the protected phone plays the appropriate tone.
A protected phone plays or does not play a tone
under these circumstances:
When the Play Secure Indication Tone option
•
is enabled (True):
–
When end-to-end secure media is
established and the call status is secure,
the phone plays the secure indication tone
(three long beeps with pauses).
–
When end-to-end nonsecure media is
established 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, no tone is played.
Allows secure phones to place conference calls
using a secured conference bridge.
As new participants are added by using Confrn,
Join, cBarge, Barge softkeys or MeetMe
conferencing, the secure call icon displays as long
as all participants use secure phones.
The Conference List displays the security level of
each conference participant. Initiators can remove
non-secure participants from the Conference List.
Non-initiators can add or remove conference
participants if the Advanced Adhoc Conference
Enabled parameter is set.
