Perhaps the most efficient way of routing telephone calls for the larger business, Du Pont Telecom leads the way in Least Cost Routing (LCR), and it could just be the answer for your business.
What is LCR?
LCR is a simple practice that “finds the most cost-effective way to route telephone calls. It is the process of analysing, selecting and directing the path of outbound and inbound communication traffic, depending on which path delivers the best rates”.
Who can use LCR?
Any organisation with interconnectivity to other networks can lower their telecom expense by selectively routing each call to the network that will complete the call at the lowest cost.
How does it work?
LCR is implemented by creating a routing table that matches telephone dialling codes to a list of destination networks ranked by cost. While routing tables can be created manually, LCR software is used. This automates the process of building an optimised LCR table with tens of millions of routes.
Until now, the LCR table has been exported directly to a telephone switch. Limitations, including switches’ limited memory and a slow export process, brought about a new technique. An external routing engine provides real time LCR instructions to one or more switches on a call-by-call basis. LCR software then pushes optimised routing tables to the routing engine, instead of directly to the switch. These engines are typically software operating on Linux-based servers with ample memory to host tens of millions of routes. When a switch receives a call, a query is sent to the engine for routing instructions and the response is returned within a few milliseconds.
