<span style="font-family: Arial, Helvetica, Sans-Serif; font-size: 12px"><div>Greetings all,</div>
<div> </div>
<div>We've got an internal tool that lets my NOC staff query extended LRN on numbers. They use this for checking the numbers current carrier, Verifying a number after it ports (In or out)..etc. This same tool also pulls CNAM from a few sources so they can easily test "Wrong caller ID" tickets.</div>
<div> </div>
<div>Does anyone have any good leads on someone that has a good non-cached LRN API?</div>
<div> </div>
<div>We've tried two thus far with poor results.</div>
<div> </div>
<div>1. "CallWithUs", Real time results, But cached for 24 hours after the first request. So if we wanted to check a number more then once a day, We get the same results.</div>
<div> </div>
<div>2. ThinQ. Results returned are either cached, Or perhaps outdated. Querying a number after it ports returns the old LRN. Results do not update until 24 hours after port. Since we have a decent bit of traffic on ThinQ, And a decent relationship with them I opened a ticket to see if it could be a adjusted. First was told that LRN takes 24 hours to update. And that was normal. I pushed back on the obvious canned and incorrect response and they "made some changes" which did nothing. Finally they admitted they could not return real-time results.</div>
<div> </div>
<div>Many of my upstream carriers are using Syniverse as their LRN source. So I reached out to them. Found my volume (~20 queries a day) is too low for them. And they don't offer any type of HTTP API, Understandably on both counts.</div>
<div> </div>
<div>Example output of our internal tool. (Queried 13212051100)</div>
