SERVICE
CONDITIONS
!Barge-in is enabled and disabled in system programming (default is disabled).
!When barge-in is in progress, the conference key ( 
P ) LED flashes on the telephone
used to initiate barge-in and remains solid on the telephone where barge-in occurs.
!When barge-in is in progress and the user (where barge-in occurs) places their existing
call on hold, the caller who initiated the barge-in is also placed on hold. When the call is
picked up again (taken off of hold), the barge-in caller is also able to resume listening to
the conversation.
!Barge-in also works for telephones programmed to only receive calls (i.e., those
telephones restricted from dialling out).
!Barge-in is not allowed during the following conditions:
• when Automatic Redial is in progress.
• when dialling is in progress.
• before an internal user answers a call or before the user initiates an outgoing external call.
• all conditions other than an external call in progress (i.e., hold, conference call, etc.). 
• the called telephone is a member of a different tenant group.
!A single line telephone cannot be used to initiate a barge-in. However, single line
telephone conversations can be interrupted.
!A telephone cannot be used to initiate a barge-in if it is part of a conference.
!A barge-in cannot be completed if the telephone that is the target of the barge-in is part
of a conference.
!If all of the conference circuits in the system are in use, no barge-in is allowed. Barge-in
requires the use of a conference circuit.
!An alert tone is sent to all parties when a Barge-In is originated.
