Dial plan tables contain information that controls how the system routes 
calls. Each dial plan configuration file consists of at least three dial plan 
tables. This section discusses these topics:

■

■

 — Must be table ID 1

■

 — Must be table ID 2

■

 — Must be table ID 3

■

CAUTION: Tables 1, 2, and 3 must exist. Do not delete them. You may 
create additional dial plan tables if necessary, but they must be numbered 
4 or higher.

If the Least Cost Routing table exists, it takes precedence over the Internal 
table. If the system cannot find a Least Cost Routing table, it attempts to 
find a corresponding entry in the Internal table. If you have entries for the 
same purpose in both the Least Cost and Internal tables, the behavior of 
the dial plan can be confusing.

See 

 next for a description of dial plan 

command syntax and structure. For a complete list and description of dial 
plan commands, including command arguments and examples, see 

Each dial plan table contains a sequence of commands. These commands 
collectively determine how calls are handled.

Most of the dial plan commands have a very similar format, as shown in
