LEAST-COST ROUTING
Least-Cost Routing is a function provided by the MD110 whose primary purpose is to automatically route outgoing calls
over the most economical trunk route available. To do this, it analyzes the dialed number to determine the call’s destination
and proceeds to the available route choices for that particular destination. The route choices are arranged in the LCR
database in ascending order of cost so that the first choice reached is the least-cost route for that destination. If the least-cost
route has a trunk available, the trunk is selected and the call completed. If not, the system may move on to the next available
choice. Least-Cost Routing can also be used to perform dialed number modification such as pre-digit number truncation or
insertion, and can provide toll call restriction.
Least-Cost Routing is typically only appropriate if more than one trunk route choice exists for routing outbound calls. If
Least-Cost Routing is required, provide the following information.
