Vonage Well the use of Focal and Boston was only for an example. I don't know what market



Well the use of Focal and Boston was only for an example. I don't know what market or carrier Pyramid3's number belongs to since I don't know his number.

But to answer your question, SunCom or any other carrier has to do an LRN lookup prior to routing a call. The LRN(Location Routing Number) has been used every since Local Number Portability was introduced. While the incumbent carrier may own the NPA-NXX 301-755 and block number 4,(example number 301-755-4321) other carriers knew where to route these calls since only 1 carrier switch could possibly own this number.

Now after LNP has occured through the country, an LRN was needed in order to locate a specific number. So when a number ports, the incumbent carrier releases the number from the switch, new carrier builds it into their switch, performs a broadcast, and NPAC database is updated. The LRN acts in the same way a routing number on a checking account would. You phone number is the checking account number and the LRN is the routing number to your bank.

When the originating provider goes to route the call, the must have the correct LRN and if they don't, they terminate the call to the old switch where number no longer exists. This is where people complain that they can't get calls from certain people and caller gets a Disconnected or not in service message. Again, not a fault of Vonage or their carrier.

In order to see where the actual call goes once it leaves SunCom would require an SS7 trap performed by SunCom to see whose Destination Point Code it hits. Focal could also do the same on their side to see whose incoming trunk group the call is coming to them on. The call from SunCom would not route to the Telco that the number ported away from. If it did, it would fail to complete as it would be terminating to their switch that no longer houses the number.

Is the information you were looking for?

Problems with inbound calls from SunCom


I have one frequent caller, on SunCom wireless who almost always has a problem.
Did you ever think that it might be a SunCom problem, not vonage. If that is the only
Yes of course, but that's neither here nor there. Any suggestion to remediate?
All calls for you will terminate through the same point from non Vonage lines to
Excellent, thank you
