A called number (or the name of the party being called) will be displayed as

of the calling party is displayed when the first ringing tone sounds if the call
originates within the same switch, and terminates on the IN CALLS key. If
the incoming call terminates at a secondary DN, the number/name will be
displayed only after the receiver is lifted.
