Re: [VoiceOps] Preventing calls to cell phones with guaranteed accuracy

It could be anytime the *LEC still has the entire A block. As far as how common it is I can't really say. My cell phone and childhood phone number are both native routed. Wireline: http://www.localcallingguide.com/lca_prefix.php?npa=732nxx=363 Wireless:

Re: [VoiceOps] Preventing calls to cell phones with guaranteed accuracy

‎Yeah, poking around metro Atlanta, which is quite pooled, there do seem to be quite a few A block assignments floating around.

Re: [VoiceOps] Preventing calls to cell phones with guaranteed accuracy

‎Aren't 95%+ rate centres pooled these days? If so, they'd still have LRNs, since LRN-guided routing is a requirement of pooling. So, who still has non-pooled 10K blocks? Is that common in metro, or largely a

Re: [VoiceOps] Preventing calls to cell phones with guaranteed accuracy

Thanks, Mary Lou. But does the NPAC have any such fields as well?Incidentally, ‎where are the COCTYPE/SSC/COTYPE fields in the LERG? I was just getting the operator designation from LERG1, and mapping LRNs from

Re: [VoiceOps] Preventing calls to cell phones with guaranteed accuracy

NPAC has a service type field that indicates wireless/wireline. That doesn't solve for native numbers though since they won't have LRN data since they don't have LRNs. I don't remember offhand if LERG has a wireless/wireline indication for a given [A]OCN or block. James Milko Architect,

I know a guy who runs a site that sells the npa nxx to carrier type at a fraction of the lerg costs On Aug 19, 2015 11:39 AM, Alex Balashov abalas...@evaristesys.com wrote: ‎Indeed, you'd start from the NPAC, which would get you, for a given TN, an LRN. Then what? ‎ -- Alex Balashov | 

Re: [VoiceOps] Preventing calls to cell phones with guaranteed accuracy

LERG 6 also has a portable indicator so you can tie into that when you are pulling information from NPAC, but you can also tell somewhat because all 10 thousand blocks of the non-portable blocks are only assigned to one carrier. There are still many rural areas that are not in mandatory pooling

Re: [VoiceOps] Preventing calls to cell phones with guaranteed accuracy

Nothing as long as companies don't offer both services. Looking up the NPA-NXX of the LRN in LERG 6 would tell you both what the service is and if the NXX is portable. Mary Lou Carey BackUP Telecom Consulting 615-791-9969 On August 19, 2015 at 1:38 PM Alex Balashov abalas...@evaristesys.com

Re: [VoiceOps] Preventing calls to cell phones with guaranteed accuracy

Their lists are already cleaned by NPA-NXX, it's just not sufficient any more because of LNP. Looks like the TCPA compliance product from Neustar, which someone else posted yesterday, is the best solution. Pretty cheap too. It's just indicates intermodal porting of a number with no other info.
