ABSTRACT:
When a call offer is received by a telecommunications peering network destined for a telephone number maintained within a peering database, the telecommunications peering network attempts to route the call directly to the peering partner telecommunications (e.g., broadband, voice over internet protocol, etc.) equipment. If the route fails with a corresponding destination unreachable failure code, the telecommunications peering network can attempt to determine whether or not the telephone number has been ported to a different provider. If the telecommunications peering network determines that the telephone number has been ported, the telecommunications peering network removes the telephone number from the peering database.
