line. Barge features include cBarge and 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.
The phones support Barge in two conference modes:
 • Built-in conference bridge at the target device (the
