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/

ATA To Connect to Mitel PBX
by nate＠blastcomm.com June 19, 2019

June 19, 2019

I've only had to provide POTS termination to 1 MITEL system. I tried using Linksys/Cisco SPA and Grandstream ATA's, then finally put in an Adtran TA904 (2nd gen). The Adtran seemed to give the least number of issues with Lines getting stuck open, Echo, etc. But the (former) customer was still complaining about some issues when they closed up shop. I now need to provide 6 analog lines to hand off to an existing MITEL. Is there an ATA that's better than a TA908 for doing "Acceptable" POTS to a MITEL? Thanks, Nate

605-562 - Arbitrage scam?
by paul＠timmins.net June 18, 2019

June 18, 2019

Is anyone else seeing lots of long duration calls to the 605-562 exchange that when you dial the respective number, it supervises to dead air? Seems like a new kind of toll fraud that international fraud detection systems won't catch. -Paul

AT&T LRN Issue?
by mwiles＠akabis.com May 29, 2019

May 29, 2019

Anyone from AT&T monitoring here? We have a customer that some AT&T customers cannot dial. I'm guessing it's related to a stale LRN. We ran into this recently with Windstream, and it was a bear to get addressed... but they finally did and admitted the error on their end. Or... anyone have a good channel to contact AT&T for such issues? Thank you, Mark

Google Voice Abuse Contact
by voiceops＠ics-il.net May 22, 2019

May 22, 2019

Does anyone have an abuse contact at Google Voice? I was recently contacted by a scammer and they directed me to contact a Google Voice number. It's via bandwidth.com, so I've reached out to them, but Google is going to have more information on the fraudster. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Looking for cost-effective eSBC that supports inband DTMF <-> RFC2833 transcoding support
by frnkblk＠iname.com May 14, 2019

May 14, 2019

We have an educational customer with an IVR that only supports RFC 2833 and an eSBC (Mitel border gateway) that cannot not perform transcoding from inband DTMF to RFC2833. There are some local VoIP to VoIP calls where the caller's device only supports inband DTMF and our softswitch cannot transcode them, so the IVR doesn't work for some parents and constituents. We'd like to recommend a cost-effective eSBC that supports inband DTMF <-> RFC2833 transcoding. Any recommendations from this group? I looked at EdgeMarc, but apparently their newer models don't have a DSP, or at least that functionality, anymore. Frank
