Tracing Suspicious Calls; Making And Receiving Secure Calls - Cisco 7970 Phone Manual

Tracing Suspicious Calls

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.

Making and Receiving Secure Calls

Depending on how your system administrator has configured your phone system, your phone might
support making and receiving secure calls. To be identified as a secure call, both your phone and the
phones of all call participants must support these security features. Additionally, the phone system
must also be able to ensure or validate the integrity of the call between the phones. If any of these
conditions are not met, the call cannot be identified as secure, even if you are speaking to someone
within your own office or company.
Your phone supports these types of calls:
• Non-secure call—When the call is non-secure, at least one of the participating phones or the
connection do not support these security features or the phones cannot be verified.
• Authenticated call—When the call is authenticated, the identities of all phones participating in the
call have been verified.
• Encrypted call—When the call is encrypted, the data in the call (your conversation) is being sent
only to the intended recipient (the other phones on the call), and it is encrypted so that no one can
tamper with it or listen in on the conversation. Encrypted calls are also authenticated.
