Configuring number substitution
Network requirements
As shown in Figure 30 , configure number substitution on the routers so departments in different areas can
call each other by using the area code of the destination area plus a four-digit local number. For example,
to use phone 1688 of the F department in area B to call phone 6788 of the M department in area A, dial
the number 0103366, in which 3366 is the number of the M department in area B. On phone 6788, the
calling number 1688 is displayed as 0211234, which is the area code of area A plus the number of the
F department in area A.
