Group-CO (G-CO) Button

To use outside (CO) lines efficiently, a group of outside (CO) lines (outside (CO) line group)
can be assigned to a CO button. This button is referred to as Group-CO (G-CO) button. Any
incoming calls from any outside (CO) line in the outside (CO) line group arrive at the G-CO
button. To make an outside call, you can access an idle outside (CO) line in the group by
simply pressing the assigned G-CO button.
• The same line can be assigned as a S-CO button and G-CO button.
• The extension for making and/or receiving calls in outside (CO) line groups must be
programmed.
• When your extension is assigned as the incoming call destination for an outside (CO) line,
you cannot receive any incoming outside calls unless a G-CO, O-CO or S-CO button
associated with the line is assigned.
