Patent ID: 8265259

Claim:
A method comprising: receiving a telephone number (TN) to test for its porting activity as part of a local number portability (LNP) order, wherein the porting activity includes at least one of port in, port out, and migration of the TN; accessing a LNP call tester (LCT) to determine a current local routing number (LRN) for the TN; and determining, based on the TN and current LRN, whether the porting activity is completed for the TN in relation to a core telecommunications carrier servicing an owner of the TN, wherein determining whether the porting activity is completed for the TN includes analyzing the status of both the current LRN and TN, and wherein if there is a target LRN for the TN and the target LRN is equal to the current LRN, then the LCT determines that the porting activity of the TN is a completed migrated, and wherein if the TN equals the current LRN and the TN is in a block of TNs owned by the core telecommunications carrier, then the LCT determines that the porting activity of the TN is a completed port in, and wherein if the TN equals the current LRN and the TN is not in a block of TNs owned by the core telecommunications carrier, then the LCT determines that the porting activity of the TN is a completed port out.
