Verizon Wireless Contact
by cwhelan＠staff.gwi.net Jan. 21, 2022

Jan. 21, 2022

Hello everyone, I know this is a long shot, but I'm hoping someone on here works for Verizon Wireless or knows someone that is in a position to assist us. Recently, a change to call routing occurred and Verizon Wireless calls are now being delivered across our tandem instead of a SIP peer. Ideally, I would like to establish a SIP trunk to Verizon Wireless but changing the call flow is the short term goal. Thanks in advance for your help!

ANIs flagged as telemarketer/spammer/scammer
by abalashov＠evaristesys.com Nov. 14, 2021

Nov. 14, 2021

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/

Enterprise Connect Orlando
by ryan.finnesey＠conovence.com July 21, 2021

July 21, 2021

It has been many years since I attended Enterprise Connect - I think the last time was back in the early 2000s. Are other members of the group attending the conference? Is it helpful to CLECs and UCaaS Providers? Should I buy a full pass or just the expo pass? Ryan

Spectrum NOC Help

If anyone from Spectrum is watching I'd send them a bottle of booze for their help (or case of beer) (or flowers).. We have a domain that keeps getting blacklisted by their DNS (Meaning it won't resolve). It's been an on again off again issue, and we have no idea why.

Connecting to Remote Tandems
by voiceops＠ics-il.net July 9, 2021

July 9, 2021

I'm evaluating methods of extending our footprint. I purposely left out company names. One of the companies we talked to was really only interested in getting us the inbound long distance calls, not the local ones. Well, they would, but the terms were vastly different. Given that I still need to build out to connect to the local tandem, what's the point in using a third party to connect to long distance? Are the terms for connecting to the local tandems different because the access tandem is simpler, whereas the local tandem could potentially involve connections to a bunch of other switches, once volume dictated I needed direct connections... and they don't want to deal with that? Are there third parties that don't have vastly different terms for local tandem services? Also, is it likely that I just don't understand what's going on? I went circles with the sales rep to make sure I understood what he was saying, but I could be wrong. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

TransNexus STIR/SHAKEN Stats
by compuwizz＠gmail.com July 8, 2021

July 8, 2021

TransNexus made a blog post https://transnexus.com/blog/2021/shaken-stats-june/ which shows the percentage of calls that had Passport headers in June. Inteliquent, Lumen/Centurylink, Frontier, Windstream, Intrado, Peerless seem to be missing from the list unless they are under the SaaS providers. I'm glad that many carriers are putting certs behind a CDN. The ones that aren't seem split between being hosted on AWS and self hosted. Validation will add to PDD, so CDNs will hopefully make it less of an issue. ~Jared

Bandwidth vs Inteliquent
by colton.conor＠gmail.com July 8, 2021

July 8, 2021

If you had to choose only between these two providers for wholesale services, which would you choose and why? We are only considering these two as the softswitch we are planning on using (Netsapiens) has only built out Group MMS support for these two carriers APIs, and no one else. I have used many services over the years that have utilized both of these carriers, but I have never had a direct relationship with them. Which has a better portal, API, and company overall? What are the true differences? Are there any resellers to consider where we would still have direct access to these carriers APIs?

interconnect directly with a PSAP?
by robverk＠hotmail.com July 7, 2021

July 7, 2021

I have been out of the game for about 20 years and now I am back. I have a lot to catch up on but I'm hoping this listserv can help me out. I have a few questions * Is it possible to interconnect directly with a PSAP? * Is a CLEC license/agreement still required? * Is this interconnection still only offered via TDM or is IP/SIP an option? Thanks for your help. Rob

interconnect directly with a PSAP?
by ptimmins＠clearrate.com July 6, 2021

The answer to all 3 is, it depends. Generally there are non clec ways to attach to 911 directly (the exact process will have to be worked out by talking to the carrier providing 911 in that area) (or indirectly through the likes of intrado or intelliquent) and at least in Michigan, the carrier who won 911 contracts throughout Michigan actually is native IP on the network, and TDM connectivity is an upcharge.
