Least Cost Routing

 

In order to provide low cost calls, Long Distance Telephony Providers must by-pass the regular telephone company to achieve competitive rates. Often service providers establish private VPNs, using emerging technologies such as "Voice Over IP", or proven technologies such as Voice Over Frame. These carriers often rely on a large number of alternative carriers to complete the network. The local public telephone companies then enter into some form of volume or other tariff arrangement and the LCR service provider usually provides one or many access-numbers to get the most effective call price around.

These alternative carriers offer varying discounts dependent on time of day and destination. To maximize all potential savings, service providers make use of LCR (least cost routing) Diallers, which can be programmed and re-programmed to re-route calls to destinations, by re-dialling them through the lowest cost alternative carrier of the moment. These are referred to as "diallers" and are small inline units between your phone and the line.

Using our dialer products as basis for example a typical customised least cost routing table is shown below... This is an actual example from one of our customer's diallers, as you can see the application of a correctly programmed dialler can save money. Although the tariff pricing may now be out of date it reflects the flexibility of the diallers.

What you can see is that for this example different codes are shown for different destinations this achieves the best possible combination of prices for this particular customer's usage.. This genuine example is typical from one of our premium diallers.
(NB spelling : diallers or dialers both words have the same meaning)
