This section provides dial program configuration examples.

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.
