Managing
the Dial Plan
Configuration File
When you place a call to an external telephone number, the system can
use these pretranslator steps to create the full 10-digit number:
1 Remove (stripLead) the first two digits (20) from the internal extension
number of the telephone making the call.
2 Add (prepend) the digit sequence 50855542 to the two remaining digits,
creating the full DDI/DID telephone number.
3 Pass the full number to the telephone company.
Example: To transmit CLIP information about outgoing calls, you can
define a pretranslator that transforms internal extensions into full
telephone numbers (the numbers that someone external to the company
uses to dial in). Assume that you use telephone extension numbers from
1000 to 1099 and that only the last two digits match the DDI/DID
numbers that are assigned to the company. You can define a
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 that 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.
Define digit manipulation operations (append, prepend, replace,
stripLead, or stripTrail) in the Routes section of the dial plan configuration
file to indicate which outgoing pretranslations you want to perform. You
can define these commands for both destination routes and timed routes.
