Bangkok Beach Telecom recently has been working with a North American Tier 3 Mobile operator to lower their cost to deliver long distance calls. The operator felt they had already done much to optimize these costs using their own in-house tools. We proposed using our Least Cost Routing model (LCR) to see if these costs could be further lowered. We charge nothing to determine the potential savings LCR may yield, and going forward is up to the operator. This operator was quite surprised to learn that a further 50% reduction in their average cost per MOU was achievable. Continue reading “Least Cost Routing Delivers for Cellular Operator”
All voice network operators are continually looking for ways to cut the cost of delivering outgoing long distance calls. The best way to do this is to use 2 or more Inter-Exchange Carriers (IEC, in FCC-speak) or what you and I might call “long distance service providers,” and cherry pick the cheaper provider for each dialed destination. This approach is called “Least Cost Routing.” Seems simple, right? Well, it’s not, really.
First there is the tyranny of numbers. A Least Cost Routing application typically will use the Local Exchange Routing Guide (LERG) to determine all possible dialed destinations. The LERG defines roughly 450,000 destinations. For each destination you might have a cost proposal from several IEC. We tried evaluating 8 IEC.
Starting late last year our long-distance network has been overwhelmed with calls to various for-free services. These services often appear to be the proverbial free lunch, with no apparent business model because the service is 100% free to the end user. Typical offerings include free conference calls or voice chat rooms. These services can completely destroy a flat-rate all-you-can-eat telephony service provider.
