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 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.
