Cisco Systems 7931G User Manual

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. 

Nonsecure call—The phone is not protected on the Unified CM server and the call status is 
nonsecure. 

For more information, see your system administrator.

There are interactions, restrictions, and limitations that affect how security features work on 
your phone. For more information, ask your system administrator.

Check the security level of a call 
or conference

Look for a security icon in the top right corner of the call 
activity area, next to the call duration timer:

Authenticated call or conference

Encrypted call or conference

Non-secure call or conference

Verify that the phone connection 
(call status) is secure.

Listen for a secure indication tone at the beginning of the call:

Secure call status—If the phone is protected, the “Play 
Secure Indication Tone” is enabled, and the call status is 
secure, a secure indication tone plays on the protected 
phone at the beginning of a call (three long beeps with 
pauses). The lock icon is also present to indicate that the 
call is secure.

Nonsecure call status—If the phone is protected, the “Play 
Secure Indication Tone” is enabled, and the call status is 
nonsecure, a nonsecure indication tone plays on the 
protected phone at the beginning of a call (six short beeps 
with brief pauses). The play arrow icon is also present to 
indicate that the call is not secure.

For more information, see your system administrator.
