Managing the Dial Plan Configuration File 43
pretranslator to remove (stripLead) the first two digits from the internal
extension number and add ( prepend ) the appropriate digit string. This
pretranslator constructs the full telephone number.
Example: If you use two different long-distance carriers at different times
of the day to save costs, you can prepend different digit sequences to the
outgoing dialed number to select which carrier you want. If you prepend
1010321 between the time the business opens and 3:00 p.m., you select
one long-distance carrier. If you prepend 1010220 from 3:00 p.m. until
the next time the business opens (including weekends), you select the
other carrier and obtain a lower rate.
To tell the system which outgoing pretranslations you want to perform,
you define digit manipulation operations (
append, prepend, replace,
stripLead, or stripTrail ) in the Routes section of the dial plan configuration
file. You can define these commands for both destination routes and
timed routes. For more information on configuring pretranslators, see
“Managing Dial Plan Pretranslators” later in this chapter.
