Telephony Features Available for the Phone
Barge Allows a user to join a non-private call on a shared phone 
line. Barge features include cBarge, Barge, and Single 
Button Barge.
  • cBarge adds a user to a call and converts it into a 
conference, allowing the user and other parties to 
access conference features.
  • Barge adds a user to a call but does not convert the call 
into a conference.
  • Single Button Barge enables users to Barge or cBarge 
into a remote-in-use call on a shared line.
The phones support Barge in two conference modes:
  • Built-in conference bridge at the target device (the 
phone that is being barged). This mode uses the Barge 
softkey.
  • Shared conference bridge. This mode uses the cBarge 
softkey.
Note The Barge and Privacy features work together. See
