Assigning Extensions to CO Lines
You must assign extensions to CO lines for out-dialing access. The following conditions apply to assigning CO lines.
• An extension that attempts access to a CO line to which it is not assigned will hear error tone and the display will
show: CO LN UNAVAIL.
• Extensions that are not assigned access to a CO line may receive that CO line via a transfer. However, once the
transferred call is disconnected, that extension cannot re-access the same CO line for use.
• Tenant Group programming of extensions and CO lines also dictates which CO lines an extension can access.
• To access a particular CO line, extension users press an available (idle) CO line button or dial a CO line group
access code (9, 740-746).
