PR Log - Jan 29, 2013 - NEW YORK -- Line-Provider.com, a leading cloud, MPLS and voice company reports that customers using their LRN LNP database service see a cost savings of upto 20 percent when compared to DNIS routing and billing.
"LRN refers to destination numbers that have been moved (or “ported”) from one carrier to another. LRN data follows the number, and allows you to rate your calls correctly, by the actual destination." states Line-Provider's VP of Carrier Relations, Marc O'Wind.
"More importantly if you are using a least-cost routing on your dialing platform, LRN allows you to route correctly using your least- costrouting software. Most wholesale customers realize a 10%-25% savings on their network bill once they start using LRN data for their USA termination."
Line-provider is now offering it's LRN database dipping service to new customers. It can be accessed via Direct Mysql query,MS SQL server query, SIP call access & code 302 return with LRN in the SIP header, or via a DNS lookup.
Over the last few months several wholesale VoIP carriers have switched from billing based on DNIS digits (Dialed Number Identification Service) to LRN based billing (Local Routing Number). LRN based billing uses local number portability data and that is causing some serious issues for SIP VoIP providers as well as outbound call centers.
One effect may be that a company thinks it is sending traffic to the lowest cost carrier in a certain area, but a ported number may be served by another carrier. When this happens, the call is suddenly billed much higher than expected.
