Secondary line
A secondary line on your phone is used as a primary line by another subscriber
of the line trunk group. Your primary line, which is configured on another tele-
phone of a line trunk group, simultaneously functions as the secondary line on
that telephone.
Phantom line
Phantom lines are not used as primary lines by any telephones in a line trunk
group. Phantom lines are established, for example, when the number of lines
provided by a communications system exceeds the number of available tele-
phones.
