ANIs flagged as telemarketer/spammer/scammer

Hi, So, of course, it is a known problem in the legitimate side of the lead engagement call centre, survey, etc. business that ANIs get flagged as "telemarketer" pretty quickly and start showing up that way on people's phones. Your normative viewpoint on that may vary depending on what you think of lead gen calls, but regardless, a reasonable person would differentiate between: (1) Legitimate outbound dialing operations that are following up with leads who provided their phone number and agreed to be called (at least, as a matter of clicking "accept" on _something_), or for some other legitimate mass-dialing purpose, and who actually own the DID inventory from which they present local-market ANIs and can in fact be reached on those numbers; (2) Illegal spammers who use fake ANIs and call people who did not in any way consent to being called by them. I am trying to learn a bit more about how this is done and what a legitimate, above-board business can do about it. Ignoring the factor of third-party call-screening apps (which most people with a mobile don't use), where is this generally implemented? As I understand it, T-Mobile do it on the network level. I have T-Mobile myself, and probably 2/3rds of unfamiliar numbers, including quite legitimate ones, show up as "Scam Likely" ? I know that's come up on the list before. AT&T displays "Telemarketer"; do they do it that way too, or do they use a Google Android feature for that which they enable as part of their carrier defaults for carrier-issued phones? What about other carriers and Android? As far as I know, Apple don't do anything like this. Do people with iPhones just not receive this "service"? How does that work? Asking where the central, or the most influential authority lies and who provides it goes to the heart of the real question, which is: what can a legitimate business do if their number has been blacklisted this way? As I understand it, the maintainers of these lists, along with the criteria for getting on them, are elusive and inscrutable, and there's really no recourse and no appeals process. I furthermore understand that this has led to the widespread approach of rotating ANIs, but that's a losing battle; they get flagged too. I imagine it won't be long before the criteria for "Scam Likely" are just "number appears to call lots of numbers in this rate centre and otherwise hasn't been around very long". But this is all just conjecture on my part; I really don't know much about how my carrier, anyone's carrier, or some BigCo that's behind my mobile OS decides that a call is a "telemarketer" or "scam" call. If anyone can shed some light on how this really works and what, if anything can be done about it, I would be most appreciative. -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Automatic 911 location updates

Is anyone doing this yet? The ability to detect the location of a phone and automatically update the 911 address? Yes, I realize it's a difficult if not impossible thing, yet thought I'd ask since a customer asked me.

Curious Caller ID issues
by darren＠2600hz.com Oct. 15, 2018

Oct. 15, 2018

Hi folks, About three weeks ago we began receiving random reports from different customers that inbound calls were displaying the Caller ID 845-789-0000. This is not the real caller ID of the originating caller, and does not appear to be their LRN, either. It is also not a scam call ? these are real, regular calls from normal humans / conversational traffic. In addition, the calls appear to originate from many different origins ? i.e. it?s not always the same caller, or destination, or city/state. The calls are real, legitimate calls, and the conversations proceed normally. But the CLID is wrong. The one thing we have narrowed down is that these calls all seem to terminate with one of our carriers ? Peerless. None of the reports we?ve received are for calls on Inteliquent, bandwidth.com, O1, etc. Peerless does not seem to be aware of any routing issue and is asking for more examples to investigate, but they?re hard to get, since it involves not only the receiving party noticing the incorrect Caller ID then prompting the caller for their real phone number and recording the date/time. (Of course, this is impossible to get clients to actually do). Oddly, a search for this number online reveals only this somewhat entertaining email thread on a Subaru mailing list https://www.subaruoutback.org/forums/138-gen-5-2015-2019/497927-curious-cel… . It describes the same symptom, and seems to equate it to an iPhone update with bluetooth, which I have a hard time believing makes any sense. If I had to really guess, it could be the rollout of VoLTE and some misconfiguration on a wireless carrier network that is only invoked when using Bluetooth to make calls ? but boy, that seems like one helluva stretch. Anyone seen this before and/or have any other ideas how to track this down? We?re running out of ideas and are tempted to just port offending DIDs away to another carrier to see if it ?fixes? the problem, but Peerless has generally been good to us so I?d really rather leave the numbers there and just sort out the issue. But, we?re short on time ? the customers are becoming irritated and don?t like providing this information to us each time the Caller ID is wrong. Any advice is appreciated. Thanks in advance!

LNP, tandems, etc.

I thought you had to be on the same tandem to port a number, but with what our tandem operator (Frontier) is telling me, this isn't the case. Comcast ported a number from us in town A. The LRN they pointed to is based in town B (per TelcoData). The tandem generally used by carriers in both towns is based in town B. Naturally, we send traffic to that tandem. The operator of that tandem is telling us that the LRN is actually homed off of a different tandem in our LATA (operated by CenturyLink) in town C. Unfortunately, I can't corroborate this information with TelcoData the only rate center I see off of that tandem in TelcoData is an AT&T town next door. Where can I read up authoritatively on the porting requirements that would apply to this and related bits of info I should know? I'm checking on our LERG access as I know that has the authoritative information, but I don't have that access at the moment. Maybe we're not subscribed to it. Number NPA-NXX in town A: https://www.telcodata.us/search-area-code-exchange-detail?npa=815&exchange=… LRN NPA-NXX in town B: https://www.telcodata.us/search-area-code-exchange-detail?npa=815&exchange=… Tandem in town B: https://www.telcodata.us/search-switches-by-tandem-clli?cllicode=DKLBILXA50T Tandem in town C: https://www.telcodata.us/search-switches-by-tandem-clli?cllicode=DIXNILXA50T Thanks. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Anyone familiar with this carrier? We've been getting a flood of FAS complaints that lead back to a media IP on their network, 77.73.68.227. One of our clients is upset that their traffic to the USA is associated in any way with Russia.
