Introduction
The Least Cost Routing (LCR) feature allows the system to automatically select the least costly 
route available according to the number dialed, the time of day/day of week, the class of 
service (COS) assigned to the station/trunk group priority level assigned. When a station user 
dials an outside number, the LCR feature analyzes the number, then automatically chooses 
an outside line from the group that is programmed as most economical.

The 6-Digit Office Code Table determines a route for one or a group of individual office codes 
within an area code. Certain office codes within an area code can be given unique or special 
routing. If the office code dialed is not found in the 6-digit Office Code Table, the call is then 
routed according to the route list table as was entered in the 3-digit table.
The system allows twenty 6-digit Area/Office...

LCR COS Priority
A station should be assigned a class of service for LCR. The LCR COS can be between 0 and 6, 
with 0 being unrestricted and 6 being the most restrictive. Within the time period route List 
table, line groups are given an LCR COS Priority assignment between 0 and 6.
A station using LCR is able to use only those CO (outside) line groups with a priority 
assignment of equal or higher value than the station’s LCR Class of Service...
