CALL FORWARDING SUPPLEMENTARY SERVICE (SS-CF) WITH REROUTING
Example 1) Station A originates a call to Station B, and Station B set to forward a call to Station C. Station
C is set a call to forward to Station B.
The call is terminated at the Station B after being forwarded to Station C.
Example 2) Station A originates a call to Station B, and Station B set to forward a call to Station C. Station
C is set a call to forward to Station D and then Station D set to Station B.
The call is terminated at the Station B after being forwarded to Station C and D.
12. When the service is used to be interworked with the interface except IS-11572 or Q-SIG, the displayed
number is as follows.
• On the caller’s LCD, the display that indicates the connected party’s number will not be changed until
the forwarded destination answers the call (If using IS-11572 or 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 destinations LCD, the display is the same as that of the forwarded station using CALL
FORWARDING service.
