Barge and Privacy
The Barge and Privacy features work with each other. Both features work with only shared lines.
Barge adds a user to a call that is in progress. Pressing a softkey automatically adds the user (initiator) to the shared-line call (target), and the users currently on the call receive a tone (if configured). Barge supports built-in conference and shared conference bridges.
The administrator enables or disables Privacy setting. When Privacy is enabled, the system removes the call information from all phones that share lines and blocks other shared lines from barging in on its calls. When Privacy is disabled, the system displays call information on all phones that have shared line appearances and allows other shared lines to barge in on its calls. Administrators configure Privacy for each device, and users toggle the Privacy feature on or off.
This chapter provides the following information about Barge and Privacy:

Introducing Barge and Privacy
The following sections describe Barge and Privacy.
Barge
Barge allows a user to get added to a remotely active call that is on a shared line. Remotely active calls for a line comprise active (connected) calls that are made to or from another device that shares a directory number with the line. Barge supports this type of remote-in-use call.
Phones support Barge in two conference modes:
•
•
By pressing the Barge or cBarge softkey in the remote in use call state, the user gets added to the call with all parties, and all parties receive a barge beep tone (if configured). If barge fails, the original call and status remain active.
If no conference bridge is available (built-in or shared), the barge request gets rejected, and a message displays at the barge initiator device.
Table 8-1 describes the differences between Barge with built-in conference bridge and shared conference.
Barge Using Built-In Conference—Barge Softkey
You can use the Barge softkey only in the remote-in-use call state. A built-in conference bridge proves advantageous because neither a media interruption nor display changes to the original call occur when the barge is being setting up. A spinning circle displays at the right side of the prompt status message window at the target device.
When the barge initiator releases the call, the barge call gets released between the barge initiator and target. The original call between the target device and the other party remains active. A barge disconnect tone (beep beep) plays to all remaining parties.
When the target device releases the call, the media between the barge initiator and the other party gets dropped briefly and then reconnects as a point-to-point call. The display changes at the barge initiator device to reflect the connected party.
When the other party releases the call, both the original call and the barge call get released.
When the barge initiator puts the call on hold, both the target device and the other party remain in the call.
When the target device puts the call on hold or in a conference or transfers it, the barge initiator gets released from the barge call while the original call also gets put on hold, in a conference, or transferred. The barge initiator can barge into a call again after the media gets reestablished at the target.
When the other party puts the call on hold or in a conference or transfers it, both the target device and the barge initiator remain in the call.
When network or Cisco CallManager failure occurs, the barge call gets preserved (like all active calls).
Some Cisco IP Phones (such as Model 7940 and 7960) have the built-in conference bridge capability, which barge uses.
The following settings activate or deactivate the built-in conference bridge:

Barge Using Shared Conference—cBarge Softkey
You can use the cBarge softkey only in the remote-in-use call state. No standard softkey template includes the cBarge softkey. To access the cBarge softkey, the administrator adds it to a softkey template and then assigns the softkey template to a device.
When cBarge gets pressed, a barge call gets set up by using the shared conference bridge, if available. The original call gets split and then joined at the conference bridge, which causes a brief media interruption. The call information for all parties gets changed to Barge.
The barged call becomes a conference call with the barge target device as the conference controller. It can add more parties to the conference or can drop any party.
When any party releases from the call, which leaves only two parties in the conference, the remaining two parties experience a brief interruption and then get reconnected as a point-to-point call, which releases the shared conference resource.
For more information, see the "Configuring Barge and Privacy" section.

Privacy
With Privacy, administrators can enable or disable the capability of users with phones that share the same line (DN) to view call status and to barge the call. Administrators enable or disable Privacy for each phone.
Administrators perform the following configuration steps to enable or disable Privacy:
•
•
•
When the device that is configured for privacy registers with Cisco CallManager, the feature button on the phone that is configured with Privacy gets labeled, and the status shows through an icon. If the button has a lamp, it lights.
When the phone receives an incoming call, the user makes the call private (so the call information does not display on the shared line) by pressing the Privacy feature button. The Privacy feature button toggles between on and off.

Interactions and Restrictions
The following sections describe the interactions and restrictions for Barge and Privacy:
Interactions
The following sections describe how Barge and Privacy interact with Cisco CallManager applications and call processing:
•
Barge and cBarge
Cisco recommends that you assign either the Barge or cBarge softkey to a softkey template. By having only one of these softkeys for each device, you can avoid confusion for users and potential performance issues.
Upgrading to Cisco CallManager Release 4.0 or Later
When a Cisco CallManager database that contains the BargeEnabled parameter is upgraded from Cisco CallManager Release 3.3 to Release 4.0 or later, the system populates privacy settings opposite the BargeEnabled setting.
Barge and Call Park
When the target parks the call, the barge initiator gets released (if using the built-in bridge), or the barge initiator and the other party remain connected (if using the shared conference).
Barge and Join
When the target joins the call with another call, the barge initiator gets released (if using the built-in bridge), or the barge initiator and the other party remain connected (if using the shared conference).
Restrictions
The following restrictions apply to Barge:
•
•
•
•
•
•
If the initiator phone is configured for encryption, the barge initiator can barge into an authenticated or nonsecure call from the encrypted phone. After the barge occurs, Cisco CallManager classifies the call as nonsecure.
If the initiator phone is configured for encryption, the barge initiator can barge into an encrypted call, and the phone indicates that the call state equals encrypted.
A user can barge into an authenticated call, even if the phone that is used to barge is nonsecure. The authentication icon continues to display on the authenticated devices in the call, even if the initiator phone does not support security.
For more information on this topic, refer to the Cisco CallManager Security Guide.
The following restrictions apply to Privacy:

The following restriction applies to built-in conference bridge:

Installing and Activating Barge and Privacy
Barge and Privacy system features come standard with Cisco CallManager software. The administrator activates the features after installation to make them available for system use. The following sections provide information about activating the features:
•
•
Activating Barge with Built-In Conference Bridge
To activate Barge with built-in conference bridge, add the Barge softkey to a softkey template, assign the softkey template to a device, set the Built-in Bridge Enable service parameter to On, and set the party entrance tone to True. See the "Barge Configuration Checklist" section for details.
Note
Activating cBarge with Shared Conference Bridge
To activate Barge with shared conference bridge, add the cBarge softkey to a softkey template, assign the softkey template to a device, and set the party entrance tone to True. See the "Barge Configuration Checklist" section for details.
Activating Privacy
To activate Privacy, set the Privacy Setting service parameter to True, add Privacy to a phone button template, assign the phone button template to a device, and choose Privacy for each device. See the "Privacy Configuration Checklist" section for details.
