to the call duration timer:
Authenticated call or conference
Encrypted call or conference

Listen for a secure indication tone at the beginning of the call:
• Secure call status: f 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.

Note
A device engaged in a call is either trusted or untrusted. Lock or shield icons are not displayed on a Cisco
Unified IP Phone screen when a call is to or from an untrusted device, even though the call might be
secure.
Note
Suspicious Call Trace
If you are receiving suspicious or malicious calls, your system administrator can add the Malicious Call
Identification (MCID) feature to your phone. This feature enables you to identify an active call as suspicious,
which initiates a series of automated tracking and notification messages
