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/

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

Outsourcing STIR/SHAKEN Setup
by dovid＠telecurve.com Sept. 9, 2020

Sept. 9, 2020

Hi, Does anyone have a recommendation for a company that get us everything needed for STIR/SHAKEN setup? By setup I mean helping us file to get a cert etc. From the small research I have done there is a lot of fragmented information out there and it would be easier for us to pay someone else to do this then invest our own time to take care of this. TIA. Regards, Dovid

Level3 issue
by dovid＠telecurve.com Aug. 30, 2020

Aug. 30, 2020

All, It seems Level3 is having a global issue. Traces from around the world to IP's that they advertise seem to loop at whichever router the traffic comes in on (e.g. in EWR it will loop at the EWR router, In Frankfurt the same).

Network Taps
by ctaloi＠gmail.com Aug. 26, 2020

Aug. 26, 2020

Planning to add a few network taps to our data center and roll out VoIP Monitor for packet tracing and analysis. I am looking to capture ~ 8 1G copper ports and 2 10G fiber ports. I would like to be able to filter based on VLAN, IP and port at the tap level (IP and port isn't totally necessary, but would be a nice to have). Any recommendations on taps to get me there? Thanks!

Vitelity Inbound SMS Outage 2210UTC 8/14/2020
by beckman＠angryox.com Aug. 14, 2020

Aug. 14, 2020

We detected an SMS outage on all Vitelity DIDs starting at 2210 UTC (6:10pm EDT) and has been ongoing for 2+ hours. Vitelity was unaware of the outage when we opened an emergency ticket at 2236 UTC, and failed to post that there was an issue until 0000 UTC 8/15/2020. We have seen ZERO inbound SMS messages in the last 2+ hours. We have not yet tested outbound. https://status.vitelity.com/incidents/4l7xs1zmb2vm Beckman --------------------------------------------------------------------------- Peter Beckman Internet Guy beckman at angryox.com http://www.angryox.com/ ---------------------------------------------------------------------------

Comcast - Data Side?
by mwiles＠akabis.com Aug. 14, 2020

Aug. 14, 2020

Anyone from Comcast monitoring here? I know it's a long shot; but, we have a wholesale partner in GA that resells our hosted services. They have Comcast internet in their office, and many of their customers also use Comcast. Within the past few weeks, they've started having degradation of voice quality; but it appears their customers/traffic not traversing Comcast are not seeing this. They test with softphone using cellular data... issue's not there. They move their office over to their backup (a WOW cable model), and so far, not seeing the issue either. Our wholesale partner opened a ticket with Comcast, and was told their level was low, and they'll be out to visit on Monday. While that could be true, it seems unlikely all of the partner customers seeing this issue also suffer from low signal levels. If there's someone with Comcast here, and would like to go the extra mile for a customer, we'd love to hear from you! Thanks! Mark

AT&T Wireless contact
by nathana＠fsr.com Aug. 14, 2020

Aug. 14, 2020

This is probably a long shot, but are there any AT&T Wireless engineers here, & one who wouldn't mind contacting me off-list? I may be misinterpreting what I'm seeing, but I think you might have a small number of MMSC servers that are down... -- Nathan
