Most USA carriers now route and bill using LRN data. The Location Routing Number (LRN) is a ten-digit number allocated in the NANP just like a telephone number. An LRN is assigned to each ported telephone number and is used to route calls through the PSTN to the switch serving the ported number.
If you are not using Summit System’s LRN Dipping Service, you are likely paying 25 – 35% more than necessary for your voice traffic, experiencing more incomplete calls than necessary, and having difficulty reconciling invoices from your vendors. Using our Location Routing Number (LRN) dipping service, you can efficiently complete calls to the correct operator while avoiding dropped or incorrect calls and unnecessary and expensive default dips charged from a local exchange carrier (LEC) – all while minimizing capital investments and operational expenses. It is in every VoIP providers interest to make sure they have access to an LRN (Local Routing Number) dipping service.
