Yeah, I guess it makes sense at a technical level. Any CLEC can, in principle, pick up a call from anywhere in the LATA at the ILEC tandems (notwithstanding issues of DEOTs and all that), and they do so with regularity. I just thought there was something in one hundred percent of ICAs that

All, I realize this may be off the beaten path for this list, but is there anybody here who is fluent in LTE networks and the standards that govern them? I'm not sure what other list would be appropriate...I looked through the 3GPP's listserv but there are a staggering number of lists and I

Right. All these products are doing is doing the NPA-NXX lookup AFTER the LNP lookup. The NPA-NXX of the LRN is the carrier of record. If it's a cell phone company NPA/NXX you're dealing with a cellphone. -Paul On 08/19/2015 07:25 PM, Carlos Alvarez wrote: Their lists are already cleaned by
