Advanced Call Handling

Understanding Barge Features

cBarge and Barge

Depending on how your phone is configured, you can add yourself to a non-private call on a shared line using either Barge or cBarge.

cBarge converts the call into a standard conference, allowing you to add new participants. (See Making Conference Calls, page 42 for more information about standard conferences.)

Barge allows you to add yourself to the call but does not convert the call into a conference or allow you to add new participants.

Tips

When you barge a call, other parties hear a beep tone announcing your presence. With cBarge, other parties hear a brief audio interruption and the phone screen changes to display conference details.

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.
