Ask The Expert - Number Portability

"Ported phone numbers have become the norm these days.  What is the best way to handle the routing challenges that come with ported numbers?"

TransNexus customers report that 40% of their calls are to ported telephone numbers. This development has a dramatic impact on least cost routing. If least cost routing is based on the dialed telephone number then 40% of all calls will not be routed to the lowest cost provider! 

At TransNexus, we suggest hosting the US Number Portability Administration Center (NPAC) database locally within your network.  In this case, when calls come through your network, your VoIP switch need only send a query to your own routing server, rather than querying the NPAC directly and incurring charges for each query.  This solution also effectively eliminates the threat of downtime or bad service from querying an external database.

Though there are multiple products that allow you to host the NPAC on your routing server, the best value by far is the TransNexus OSPrey-NP routing server.  At an eighth of the cost of similar hardware, the OSPrey-NP simply and easily gives you instant and controlled access to near-real-time number portability data and routing information.
