How can this be determined? I'd imagine that only those with direct access to the "which number belongs to which provider" database could see that a given number belongs to $comapniesKnownToOfferTraditionalPhysicalService versus $comapnyKnownToOnlyDoVOIP can know this for sure? It it just that some companies with this access are selling a "we'll look that up for you" service? Or is it simpler and i'm just over thinking it?
