1.3.17  Conference Group Call
You can call multiple parties, assigned as members of a group (conference group), and establish a multiple
party conversation with the called parties. You can make a conference group call to both extensions and CO
lines (including analog lines). The following two modes are available: 
• Conference Mode: the called parties can join the conversation automatically. (  Conference Mode)
• Broadcast Mode: the called parties can hear the caller’s voice announcement, and then be allowed to
join the conversation by the caller. (  Broadcast Mode)
• If you dial a conference group number that is in use for another conversation, you will hear
a busy tone and cannot establish a multiple party conversation.
• If you fail to seize idle CO lines necessary for all members assigned in the conference group,
you will hear a reorder tone and cannot make a conference group call.
• When making a conference group call to an outside party, the CLIP number for that call will
be the one you select for making calls to a CO line. Refer to "1.3.54  Private Network
Features—CLIP (Calling Line Identification Presentation)".
 Conference Mode
If this mode is selected through system programming, the called parties can join the conversation simply by
going off-hook. The caller can end the conversation with a specific party manually.
