Cisco IP Phone 7970 Series 33

Preventing Others from Viewing or Joining a Shared-Line Call

If you share a phone line, you can use the Privacy feature to prevent others who share the line from
viewing or barging your calls (adding themselves to calls on the shared lines using the Barge or cBarge
feature).
Tips
•If the phone that shares your line has Privacy enabled, you can make and receive calls using the
shared line as usual. However, you cannot add yourself to existing calls on the shared line, and the
barge softkeys will not be available to you.
•The Privacy feature applies to all shared lines on your phone. Consequently, if you have multiple
shared lines on your phone and Privacy is enabled, coworkers will not be able to view or barge
calls on any of your shared lines.
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.
