Adding New Dial Plan Tables
■
CAUTION: The dial plan must include Tables 1, 2, and 3. Do not delete
them. You may create additional dial plan tables if necessary, but you
must number them 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
"Dial Plan Command Format"
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

Plan Configuration File Commands"

Dial Plan Command
Each dial plan table contains a sequence of commands. These commands
Format
collectively determine how the system manages calls.
Most of the dial plan commands have a similar format, as shown in
