Dial Plan Tables

Example: When voice mail arrives, the NBX system dials the telephone
number of the user’s pager. Typically, you use a system-wide prefix to
designate the device or devices you want to use for outdialing purposes,
including off-site notification calls.
Example: If the user’s pager number is 800-555-3751, and the
system-wide prefix digit is 9, the system dials 98005553751 to send
a call to the user’s pager.
To tell the system to dial a single Line Card port or a restricted number of
Line Card ports, create a suitable pool of Line Card ports for that purpose,
and then use an existing set of dial plan table entries (such as the entries
that begin with 8) or create a new set of entries to allow the dial plan
devices to route calls via the selected line card ports.
Example: You set up one 4-port card to handle all off-site notification calls.
You create a set of entries in the Internal dial plan table that each start
with the digit 8. You define a route to the 4-port card for all of these dial
plan entries so that whenever the system acts on one of these entries, it
uses one of the 4 ports on that card to dial out and notify the user.
To apply different off-site CoS restrictions to different users, you need
multiple dial plan entries. If you are not trying to apply the CoS
restrictions, then a single dial plan entry is sufficient.
Dial Plan Tables
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:
■
Dial Plan Command Format
■
Internal Dial Plan Table
— Must be table ID 1
■
Incoming Dial Plan Table
— Must be table ID 2
■
Least Cost Routing Dial Plan Table
— Must be table ID 3
■
Adding New Dial Plan Tables
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.
