Spamming for a week: 463-20X-XXXX
A bunch of numbers out of Indiana have been spamming my customers for about a week. Most are automated recordings about how your Google business listing is wrong and needs to be fixed so customers can find you. Sometimes it's a human prefixed by the telltale "BWOOP" sound. +14632000068 - BANDWIDTH.COM CLEC LLC IN +14632001925 - BANDWIDTH.COM CLEC LLC IN +14632004002 - BANDWIDTH.COM CLEC LLC IN +14632005772 - BANDWIDTH.COM CLEC LLC IN +14632006038 - BANDWIDTH.COM CLEC LLC IN +14632006422 - BANDWIDTH.COM CLEC LLC IN +14632006730 - BANDWIDTH.COM CLEC LLC IN +14632009587 - BANDWIDTH.COM CLEC LLC IN +14632018300 - BHN IP ENABLED SERVICES LLC +14632018413 - BHN IP ENABLED SERVICES LLC +14632018586 - BHN IP ENABLED SERVICES LLC +14632018682 - BHN IP ENABLED SERVICES LLC +14632027042 - LEVEL 3 COMMUNICATIONS LLC IN (Lumen) +14632027073 - LEVEL 3 COMMUNICATIONS LLC IN (Lumen) +14632027200 - LEVEL 3 COMMUNICATIONS LLC IN (Lumen) +14632027252 - LEVEL 3 COMMUNICATIONS LLC IN (Lumen) +14632027397 - LEVEL 3 COMMUNICATIONS LLC IN (Lumen) +14632027539 - LEVEL 3 COMMUNICATIONS LLC IN (Lumen) +14632027678 - LEVEL 3 COMMUNICATIONS LLC IN (Lumen) +14632027899 -LEVEL 3 COMMUNICATIONS LLC IN (Lumen) +14632030946 - METROPCS INC (T-Mobile US) Kinda hard to believe the big boys haven't caught this abuse of their network yet.

Shameless plug: for mobile devices, consider YouMail. If the ANI are already known, the free version should do a decent job of blocking them. For spoofed/one-and-done campaigns, the better option is the paid version with the captcha for non-contacts. On Wed, Mar 18, 2026 at 9:19 AM Alex Balashov via VoiceOps < voiceops@voiceops.org> wrote:

That's why YouMail works with the ITG and others :) The problem with the Google Business Listing spam is proving that criminal harm has actually happened to a real person. Our sensor network sees these calls all day, but without proof of someone getting scammed there's little interest in spending the resources. Someone would need to bait them with a traceable financial transaction to make any headway, or prove the calls alone are inflicting actual harm to a business or person. You could make the case that the calls are costing your business, but that's just it, *you* have to establish this before any LEA will act.

It's always fun when they call one of our unpublished test numbers and one of the CO techs decides to stay on the line to talk to an agent and have some fun* with them. * Legal, legitimate fun -- ie: informing them that the call is being recorded for security and training purposes, quizzing them on how they got the number, etc. On Wed, Mar 18, 2026 at 12:28 PM Alex Balashov via VoiceOps <voiceops@voiceops.org> wrote:

Oh yeah, I've talked to them plenty. And if you've been on the list for any amount of time, you know I am not a man of few words. But wasting their time with meandering and circuitous existential chats hasn't got them to stop calling. -- Alex

It's always fun when they call one of our unpublished test numbers and one of the CO techs decides to stay on the line to talk to an agent and have some fun* with them.
* Legal, legitimate fun -- ie: informing them that the call is being recorded for security and training purposes, quizzing them on how they got the number, etc.
I look up the call while I'm talking to them to see which trunk it came in on and to review the Identity header. In at least one instance, I had a traceback request completely filled out before the call was over. Just needed to end the call to download the audio file. "So gift cards from the Walmart should work?" "Yes." "And just to be clear, you work for the US government, with the IRS?" "Yes." "Perfect. That should be everything I need to complete this traceback form. You do realize you called a telephone company, right?"
I did devise a new one yesterday that seems to get them to hang up quickly. I request a transfer to a live agent, then: Me: [seemingly ignoring the call centre agent and talking to someone across the room] "Sandy, go ahead and conference the FBI in on this one, huge fraud." -- Alex

Never give any company your cell number. Just don’t. I’ve tracked this, I generate new numbers for many common needs, such as recently, refinancing a loan. The amount of garbage suddenly sent to that new number is unreal. It was a number we’ve had for nearly ten years unused, clean. I have one generic personal number that I use for companies. It just goes to VM. I can’t picture what company needs to talk to me NOW instead of leaving a message. Funny story: An Indian-run dry cleaner, and Indian-run store have actually been offended by this. They said they would text me, and I said they can’t because it’s a landline. The dry cleaner in particular was super perturbed that she “can’t send me coupons and reminders to get things cleaned” and then more pissed when I said those are ads I don’t want. The c-store nearly told me to just get out. WTF. On Mar 18, 2026 at 8:40:47 AM, Alex Balashov via VoiceOps < voiceops@voiceops.org> wrote:

I wish my upstream (Twilio) had a big "Flag as Spam" button or API call that would send all the relevant info to whomever needs to know.
E-mail sorta has spam reporting handled, but Voice/SMS doesn't appear to have that sorted out yet.
I have been receiving the "tax resolution center" / "loan determination" / "debt consolidation" scam calls, many of them from TFNs, for close to a year at this point. They often overwhelm my phone, sometimes several come in at the same time from different DIDs, and they often interrupt other tasks or calls.
I don't know what to do about it other than change my number (TMO), which I'm unwilling to do with how much 2FA and business stuff is tied to it. Turning on the iOS "ignore calls from unfamiliar numbers" is also totally not an option because I get lots of legitimate calls from unfamiliar numbers. It's really, really, really bad. I seem to have been singled out for an exceptional volume of these.
I have on occasion pressed '2' on their IVR to speak to an "agent". The transfers are instant with no hold time. 100% of "agents" have been Indian.

FWIW, I've been getting one of these from more local numbers to me (Georgia) every day for the last 3 months.
I also get about 10 calls a day on my mobile from the "loan approval dept" / "tax resolution centre" / "underwriting dept" / "determination office" from all manner of random national DIDs and have absolutely no idea what to do about it. I report them all as spam, but it's a new number every time.

Kinda hard to believe the big boys haven't caught this abuse of their network yet.
I tried reporting the numbers to bandwidth.com (as ID'd by telcodata.us), but their form only allows for a single entry at a time, and it says most of the numbers don't belong to them. Either their form is broken or telcodata.us is out of date.

The calls I am receiving are of a different nature than the ones Aaron is complaining about. On the rare occasion I've called back one of the hundreds or thousands of numbers that have called me with the particular scam I'm referencing, they seem to go to the intended scam entity, and proffer the same scam IVR, offering transfers to the same scam agents.

So...did you get any Identity headers? A traceback with ITG, or maybe an Identity header, is your only hope for tracing the origin. I'm including the below, not to say that you, Aaron, don't know this, but just in case it's valuable to anyone else reading: In the case of your first number, it belongs to a thousand block assigned initially to Bandwidth.com <http://bandwidth.com/>...but that's not even meaningful for routing a call to them today. You'd have to do an LRN lookup to find out how to deliver a call back to the legitimate owner of this number. I did an LRN lookup for that first one, and it's currently ported to Onvoy, one of the brands of Sinch. But again, that only tells us how to get a call TO that legitimate owner. What you want to know is how they're sending calls to you. And if you're getting an Identity header it would be at least interesting.

In the case of your first number, it belongs to a thousand block assigned initially to Bandwidth.com...but that's not even meaningful for routing a call to them today. You'd have to do an LRN lookup to find out how to deliver a call back to the legitimate owner of this number.
I did an LRN lookup for that first one, and it's currently ported to Onvoy, one of the brands of Sinch. But again, that only tells us how to get a call TO that legitimate owner.
What you want to know is how they're sending calls to you. And if you're getting an Identity header it would be at least interesting.
Failing that, you can file a report with the Industry Traceback Group to report illegal calls:

Kinda hard to believe the big boys haven't caught this abuse of their network yet.
I tried reporting the numbers to bandwidth.com (as ID'd by telcodata.us), but their form only allows for a single entry at a time, and it says most of the numbers don't belong to them. Either their form is broken or telcodata.us is out of date.
I can't find a reporting for Level3/Lumen. They seem to be geared towards "I'm a customer and need help figuring out the star code to block calls".

Does Twilio give you an X-Twilio-Verstat? That might give you a clue. You can try to get the Identity header. You can go directly to the Industry Traceback Group, but it sounds like in your situation you may not be eligible to receive the information (there are legitimate sensitivities, and the info is used for law enforcement.) Many ITG queries are launched by State Attorneys General, so if you file a complaint they may go that direction. It's always best to have a recording of the call with detailed call timestamps, when filing a traceback request or legal complaint. The punchline is - LRN and number assignment are irrelevant for tracing the source of a call. They are involved when you are sending a call to that number. But the routing of calls from a particular source to you can take an entirely different path.

In the case of your first number, it belongs to a thousand block assigned initially to Bandwidth.com...but that's not even meaningful for routing a call to them today. You'd have to do an LRN lookup to find out how to deliver a call back to the legitimate owner of this number.
I did an LRN lookup for that first one, and it's currently ported to Onvoy, one of the brands of Sinch. But again, that only tells us how to get a call TO that legitimate owner.
What you want to know is how they're sending calls to you. And if you're getting an Identity header it would be at least interesting.
Failing that, you can file a report with the Industry Traceback Group to report illegal calls:

You can get media from Twilio but be careful - the last time I dealt with them on this I had several calls with them where I requested features be added because at the time (2023) it was all or nothing. You could not have them enable RTP capture on a single test number. This may have changed, but definitely something to keep in mind and get clarity on if you do want media from them.

Correct. But I can opt to record calls on my end after making sure it says "Calls may be recorded for quality and training purposes"....which is funny because the stupid automated spam just talks right over the message. -A On Thu, Mar 19, 2026 at 7:35 AM Jeff Brower <jbrower@signalogic.com> wrote:
Hi Aaron,
Ok thanks. So what they make available from their dashboard is SIP traffic, not media.

It's available under their Logs -> Calls -> <pick a call> menu.

It's just the SIP packets between Twilio and your phone server when you're using their SIP Trunking product.

Twilio does have the original Identity headers, assuming the call did not originate on TDM. You can request that these be forwarded to you rather than being replaced by their verstat TN-Validation headers.

Mark's response regarding the SHAKEN Identity header is the best suggestion. These Google Business Listing calls are made by the millions, and they come from thousands of different ANIs. Chasing ANIs is hopeless. And even if you find and reach out to the source, they are unlikely to stand down. They already know virtually nobody wants their calls. Your best bet is to see who is signing the calls; it is most likely (but not guaranteed) that they are being signed by one or a few specific small providers specializing in these calls. You (on behalf of your customer(s)) can then elect to divert or block those calls. What is the specific message(s) your customers are hearing? We see these examples frequently, in addition to others: (recorded) Hi. It seems there is an issue with the keywords attached to your Google business listing. Your Google business listing has been flagged for review by the business listing specialist. To avoid any suspension or verification issues, please press 4 to speak to an authorized representative to take care of this. To address this immediately, press 4. This will only take a few minutes. To opt out, press 9 or call (959) 262-8948. (live) Hi. Am I speaking to the business owner? Hi, sir. This is Diana. Am I speaking to the business owner? Okay. That's great, sir. We are reaching out to you in reference to the Google Business profile for your company. Because upon checking here, sir, your Google Business listing has not been properly claimed or verified. This can cause your business to display incorrectly or, in some cases, not to display at all. Are you aware of this? Oh, okay, sir. Thank you.

It's worth noting that the 463 area code in Indianapolis is pretty new - only a couple years old in practice. I would expect records of who has what to be pretty clean at this point. There shouldn't be a whole lot of serial port (no not that kind) activity on 463 numbers yet, and if you find it, that might be an indication of nefarious activity on its own. One level of port from an established CLEC to a VoIP carrier is pretty normal from my (limited) experience, though. Most VoIP carriers don't have direct assignments even if they could get them. They mostly just seem to get them from established CLECs.

The tracebacks.org route was killed pretty quick. Their response: Thank you for the information. Tracebacks are generally run based on evidence acquired from ITG members, enterprise partners, or government partners, including data analytics companies, about illegal call campaigns, so that our team can best prioritize tracebacks to ensure the greatest impact. To ensure the broadest impact, the ITG typically cannot run tracebacks based on a request from any individuals or enterprises. We recommend that you provide this information via complaints to the FCC, FTC, Law Enforcement and/or the office of your state attorney general. Such authorities often aggregate complaints and make referrals to the ITG based on what they are seeing most impacting consumers, in turn helping our team prioritize accordingly. -A On Wed, Mar 18, 2026 at 9:04 AM Kili Land <kili.land@gtt.net> wrote:

Kinda hard to believe the big boys haven't caught this abuse of their network yet.
I tried reporting the numbers to bandwidth.com (as ID'd by telcodata.us), but their form only allows for a single entry at a time, and it says most of the numbers don't belong to them. Either their form is broken or telcodata.us is out of date.
I can't find a reporting for Level3/Lumen. They seem to be geared towards "I'm a customer and need help figuring out the star code to block calls".

Their response:
Thank you for the information. Tracebacks are generally run based on evidence acquired from ITG members, enterprise partners, or government partners, including data analytics companies, about illegal call campaigns, so that our team can best prioritize tracebacks to ensure the greatest impact. To ensure the broadest impact, the ITG typically cannot run tracebacks based on a request from any individuals or enterprises. We recommend that you provide this information via complaints to the FCC, FTC, Law Enforcement and/or the office of your state attorney general. Such authorities often aggregate complaints and make referrals to the ITG based on what they are seeing most impacting consumers, in turn helping our team prioritize accordingly.

Seems like it would be a lot easier to get AI to write a simple app where people can dump known-bad numbers in, and automatically exchange them with other people...sorta like how it gets handled in the email world. It can be up to the receiving phone system to do something with it--drop the call, challenge the user to solve 3+4, mail in picture of them with a copy of their phone bill while holding a copy of tomorrow's newspaper signed and witnessed by a notary, etc... -A On Wed, Mar 18, 2026 at 1:59 PM Calvin E. <calvine@gmail.com> wrote:

The mobile carriers do this today via parties like First Orion, Hiya, TNS, while YouMail and a few others do this for consumers/wholesale carriers/enterprises. There are problems with false positives and redress. Sadly, STIR/SHAKEN didn't end spoofing, and it's still possible for a bad actor to sully the reputation of a legitimate party. That's why they set up freecallerregistry.com to help people get their "SCAM LIKELY" caller ID fixed. The system you're describing takes money to operate and maintain. Who is going to pay for it?

Just to follow up on this... Twilio doesn't expose the headers, so I have no way of knowing which carrier is allowing these spam calls to originate. Contacting Twilio and asking them to report it results in their techs asking for a detailed list of every zarking call SID and account SID, followed by "Sorry, those calls don't originate from Twilio". When pushed to contact the offending carrier on my behalf they say they don't store that information on their systems so they can't do anything, just block the prefix in your phone system. I guess it's in Twilio's best interests to let the spammers keep calling as they get to nickle and dime me for each call. -A On Wed, Mar 18, 2026 at 8:22 AM Aaron C. de Bruyn <aaron@heyaaron.com> wrote:
