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. 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.
