f" is assigned. Normally, calls arrive at extension A using either of these two extension numbers.

Figure 2 is a state diagram when incoming calls are forwarded using the device shown in Figure 81, and Figure 3 is a diagram showing the destination after forwarding, in which call forwarding settings are made from iA, so the call forwarding setting number '''' is shown.
