see one possible way accomplish this using the Dial Plan configuration
file.
Outbound Call Processing
The NBX 100 processes outbound calls using the Internal Dial Plan table
or the Least Cost Routing table.
If the Least Cost Routing table exists, it takes precedence over the Internal
table. If the NBX 100 tries to execute an entry in the Least Cost Routing
table, but can not, it does not attempt to find a corresponding entry in
the Internal table. If you have entries in both the Least Cost and Internal
tables for the same purpose, the behavior of the dial plan can be
confusing.
Example: If a new entry in the Internal table appears not to work, it is
possible that the NBX 100 is using an entry from the Least Cost table
instead. To avoid such conflicts, you can accomplish least cost routing
using only the Internal table. 3Com strongly recommends that you keep
the Dial Plan as simple as possible by using only the Internal table.
You can add entries to the Internal Dial Plan table to match the NBX 100
to the telephone service you have.
Example: the company is located in New York, and has two long distance
telephone carriers: ABC, which provides a low-cost service to four Boston
area codes (508, 617, 781, and 978); and DEF, which provides service to
the rest of the United States. You want to use one 4-port line card,
connected to analog trunk lines owned by ABC, for all calls to the Boston
area. You want to use the T1 line, which you lease from DEF, for all other
long distance calls within the United States. See “Sample Solutions Using
Dial Plan Configuration File Commands” on page 119 to see one possible
way to accomplish this using the Dial Plan configuration file.
Pretranslators
The NBX 100 uses Pretranslators to modify digit sequences of incoming
or outgoing calls. On incoming calls, pretranslators allow the entire dialed
number, including area code, to be mapped directly to an internal
extension number. For example, an external party dials 978-790-0101 to
reach the person on extension 101. Pretranslators ensure that this full
number is mapped to the correct extension number.
