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/

LNP, tandems, etc.
by voiceops＠ics-il.net Oct. 6, 2018

Oct. 6, 2018

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

Question about billing on SIP trunks
by pdcraw27＠gmail.com Sept. 24, 2018

Sept. 24, 2018

Hello voice-ops: Enterprise admin here. We just converted from ISDN to SIP (and changed providers) and we're seeing some undesirable billing behavior. I'm hoping I can get some objective feedback from different providers. If a call comes into our system, and we forward it off-net using the SIP trunks (using either "standard" call forwarding or a call forking/paralleling feature like Avaya's EC500 or Cisco's Single Number Reach), we send the call with the SIP FROM header of the original caller (which is desirable to preserve callerID). We also include a Diversion Header with one of our phone numbers (the original destination of the call). We're being billed based on the *original* calling number, which sometimes results in long distance charges, even if this leg of the call is local to us. This is particularly onerous if the inbound call is international! So, the question is- what *should* we be billed on: FROM or DIVERSION. At one point, the provider indicated that P-Charge-Info was supported, but now backing away from that. Do we have any recourse (technical or otherwise)? Thanks.

Current state of the LCR art
by dave＠socket.net Sept. 6, 2018

Sept. 6, 2018

All, I?m interested in learning about current best practices regarding LCR in the CLEC context (~2M minutes / month of LD traffic). What software/vendors are you using (or avoiding)? What are the non-obvious pros and cons? How automated is your system / how much labor do you put in? What percentage are you saving over one provider with a good rate deck when all costs are considered? Any insights are appreciated. I?m cross-posting this on the FISPA CLEC list, so I apologize if I hit you twice. Thanks, Dave Sill Manager of Business Intelligence and Automation Socket Telecom
