12. When the service is used to be interworked with the interface except Q-SIG, the displayed number is as
follows:
On the caller’s LCD, the display that indicates the connected party’s number is not changed
until the forwarded destination answers the call. (If using Q-SIG interface, the display is
changed when the call is forwarded and the called party starts to ring.) After the call is
answered, the display is changed from the caller number to the destination’s number.
On the destination’s LCD, the display is the same as when the call is forwarded using the CALL
FORWARDING service.
