Barge and Privacy

Information About Barge and Privacy

Barge and cBarge

The Barge feature enables phone users who share a directory number to join an active call on the shared line by pressing a softkey. When the initiator barges into a call, a conference is created between the barge initiator, the target party, and the other party connected in the call. Parties see the call information on their phones and, if the conference join tone is configured, hear a tone.

If a phone that is using the shared line has Privacy enabled, call information does not appear on the other phones that share the line and the call cannot be barged. Connected parties hear the barge tone (single beep) after the conference is set up. When a party leaves the conference, a barge leave tone is played to the remaining parties.

From Cisco Unified CME Release 11.7 onwards, cBarge feature is supported on Cisco 4000 Series Integrated Services Router.

From Cisco Unified CME Release 12.0 onwards, cBarge feature is supported with mixed shared line.


Note

  • Cisco Unified IP Phone 69xx series do not support cBarge with Unified CME.

  • Barge and Cbarge softkeys on SIP Phones are supported only on shared lines.

Barge (SIP)

Barge uses the built-in conference bridge on the target phone (the phone that is being barged) which limits the number of users allowed to barge. A barge conference supports up to three parties. If more users want to join a call on a SIP shared line, cBarge must be used. The SIP phone requires the built-in conference bridge to use Barge. Barge is supported for SIP shared-line directory numbers only.


Note

If a phone user barges into a barge conference, the conference is converted to a cBarge conference.

cBarge (SCCP and SIP)

The cBarge feature uses a shared conference resource which allows more than one person to barge into the call. A cBarge conference supports the maximum number of parties provisioned on the centralized conference resource. The centralized conference resource must be provisioned to use cBarge. cBarge is supported on SCCP shared octo-line directory numbers and SIP shared-line directory numbers.

When any party releases from the call, the call remains a conference call if at least three participants remain on the line. If only two parties remain in the conference, they are reconnected as a point-to-point call, which releases the conference bridge resources. When the target party parks the call or joins the call with another call, the barge initiator and the other parties remain connected.

Table 1 describes the differences between Barge using a built-in conference bridge and cBarge using a shared conference bridge.

Other party releases call

All three parties are released.

Media break occurs to release the shared conference bridge when only two parties remain and to reconnect the remaining parties as a point-to-point call.

Target puts call on hold and performs Transfer, Conference, or Call Park.

Initiator is released.

Initiator and the other party remain connected.

If no conference bridge is available, either built-in at the target device for barge or shared for cBarge, or the maximum number of participants is reached, Cisco Unified CME rejects the barge request and an error message displays on the initiating phone.

The barge and cBarge soft keys display by default when a phone user presses the shared-line button for an active remote-in-use call. The user selects either barge or cBarge to join the shared-line call. When there are multiple active calls on the shared line, the barge initiator can select which call to join by highlighting the call.

You can customize the soft key display with a soft key template. For configuration information, see Configure the cBarge Soft Key on SCCP Phones or Enable Barge and cBarge Soft Keys on SIP Phones.


Restriction

cBarge operation on an existing ad-hoc or meet-me conference is not supported.

Privacy and Privacy on Hold

The privacy feature enables phone users to block other users who share a directory number from seeing call information, resuming a call, or barging into a call on the shared line. When a phone receives an incoming call on a shared line, the user can make the call private by pressing the Privacy feature button, which toggles between on and off to allow the user to alter the privacy setting on their phone. The privacy state is applied to all new calls and current calls owned by the phone user.

Privacy is supported on SCCP octo-line directory numbers and SIP shared-line directory numbers.

Privacy is enabled for all phones in the system by default. You can disable privacy globally and enable it only for specific phones, either individually or through an phone template. You can also enable the privacy button on specific phones. After a phone with the privacy button enabled registers with Cisco Unified CME, the line feature button on the phone gets labeled “Privacy,” a status icon displays, and if the button has a monitor lamp, it lights when privacy is active. For Extension Mobility phones, you can enable the privacy button in the user profile and logout profile.

The Privacy on Hold feature prevents other phone users from viewing call information or retrieving a call put on hold by another phone sharing the directory number. Privacy on Hold is disabled for all phones in the system by default. You can enable Privacy on Hold globally for all phones. To disable Privacy on Hold on individual phones, you must disable Privacy on those phones.

The Privacy feature applies to all shared lines on a phone. If a phone has multiple shared lines and Privacy is enabled, other phones cannot view or barge into calls on any of the shared lines.

For SCCP configuration information, see Enable Privacy and Privacy on Hold on SCCP Phones.

For SIP configuration information, see Enable Privacy and Privacy on Hold on SIP Phones.

Configure Barge and Privacy

Configure the cBarge Soft Key on SCCP Phones

To enable a phone user to join a call on an octo-line directory number by pressing the cBarge soft key, perform the following steps. The cBarge soft key is enabled by default. This task is required only if you want to change the order of the soft key display during the remote-in-use call state.


Restriction

  • Supported only on octo-line directory numbers.

  • Not supported for meet-me conferences.

  • Not supported if phone user is already connected to the same ad hoc conference on the octo-line.

Enable Barge and cBarge Soft Keys on SIP Phones

A phone user can join a call on a shared line by pressing the Barge or cBarge soft keys. The Barge and cBarge soft keys are enabled by default on supported SIP phones. Perform the following steps only if you want to change the order or appearance of soft keys displayed during the remote-in-use call state.


Restriction

  • Supported only on shared lines.

For Unified CME to support Barge functionality on Cisco IP Phone 7800 Series, you need to configure the CLI commandservice phone LineKeyBarge 2 under telephony-service configuration mode. 


telephony-service
 service phone LineKeyBarge 2

The CLI command service phone LineKeyBarge 2 activates the Line keys on the Cisco IP Phone 7800 Series so that it displays the "remote-in-use" state softkeys correctly. When the command is not configured, the phones will not display the remote-in-use state softkeys. To update the phone configuration with the LineKeyBarge option, you need to execute the CLI command create profile under voice register global configuration mode.


Note

If the remote-in-use state softkey configuration has both Barge and cBarge configured, then cBarge is taken as the preferential feature. The phones will ignore the Barge configuration.
