DNIS versus LRN Billing Causing problems

Feb. 12, 2010 - PRLog -- ne issue facing a lot of SIP providers today is over the last month an increasing number of carriers now bill for calls based on LRN (Local Routing Number) where they were previously billing based on DNIS digits (Dialed Number Identification Service).

The move from DNIS-based billing to LRN-based billing creates multiple issues for the SIP provider, but there are a couple that we encounter most frequently.

The first issue is that many SIP providers don’t have a billing system that is either capable of or has been provisioned for LRN-based billing. Billing is demanding enough on a day to day basis and most SIP providers don’t need the added burden of either transforming or upgrading a billing system from DNIS-based billing to LRN-based billing.

The second issue is the underlying cost for services on routes that bill based on LRN vs routes that bill based on DNIS digits. LRN-based billing will typically increase a SIP provider’s per minute cost between 15 to 25%. If a SIP provider can’t bill their end user accordingly, profit margins either become squeezed, or they aren’t there at all.

Wholesale SIP Termination provider http://siptrunks.org today announced that they are fortunate enough to be able to offer a Verizon direct SIP route that bills based on DNIS digits and not LRN. The rates are extremely competitive, and when the 15 – 25% cost savings for DNIS-based billing is factored in, it becomes extremely compelling. We are also able to offer SIP providers LRN based billing for their customers while we bill our route based on this DNIS.

They have had this route in service for a little over a year now, and the performance is what is expected of a direct Verizon route and customer satisfaction remains very high,. Please contact dnis@siptrunks.org if you would like to discuss this route in detail.
