Tips
• If a phone that is using the shared line has Privacy enabled, call information and barge softkeys
will not appear on the other phones that share the line.
• You will be disconnected from a call that you have joined using Barge if the call is put on hold,
transferred, or turned into a conference call.
Preventing Others from Viewing or Barging 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 (adding themselves to) your calls.
Tip
If the phone that shares your line has Privacy enabled, you can make and receive calls using the shared
line as usual.
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.
Your phone can support these types of calls:
• Authenticated call—The identities of all phones participating in the call have been verified.
• Encrypted call—The phone is receiving and transmitting encrypted audio (your conversation)
within the Cisco IP network. Encrypted calls are also authenticated.
• Non-secure call—At least one of the participating phones or the connection does not support these
security features, or the phones cannot be verified.
