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.
Using Barge Features
The table below describes how to use barge features (cBarge or Barge) to add yourself to a call on a
shared line.
Tips
• When you barge a call, other parties he ar a beep tone announcing your presence. With cBarge,
other parties hear a brief audio interrupt ion 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 so ftkeys
will not appear on the other phones that share the line.
• You will be disconnected from a call that you have joine d using Barge if the call is put on hold,
transferred, or turned into a conference call.
