SS7 Landscape
by voiceops＠ics-il.net Oct. 24, 2023

Oct. 24, 2023

We currently get our SS7 via TNS. I (maybe incorrectly) understand them to be a big dog in that space. I've had two major problems with them in six months. What are my alternatives? Are they less pleasant? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Anti-robocall/compliance solutions
by calvin.ellison＠voxox.com July 28, 2022

July 28, 2022

Not an ad, just context: We're offering our internal anti-robocall filter as a compliance solution for other transit carriers and gateway/point of entry carriers. This includes DNO filtering, reputation/fraud/compliance scoring, LNP-adjusted neighbor spoofing, and some other magic. It is implemented as a SIP or API endpoint that is dipped as early as possible in the call flow. Our internal tool works well for our own purposes, but that doesn't mean it is fit for others as-is. For example, we put all the data in a search index to perform ad-hoc queries, create visualizations, and build dashboards. Is that useful to anyone else? Would other carriers prefer file-based reports sent by email or alerts via webhook, or want the data sent to their own backend? What would others expect from a user interface? Does anyone care what technologies are used internally? What about latency, pricing, and on-premise versus cloud? The list goes on. There's plenty of information online about product design in general, but not so much about what transit carriers actually need or want from a product like this. I'd especially like to hear from anyone that is still shopping for a solution, doesn't like the one they chose, or absolutely loves theirs and wants to share the reasons why. If anyone is interested in beta-testing our existing in-house solution to give feedback, please contact me off-list.

9-8-8 dialing when an outside line access code (9) is being used
by David.Zilk＠cdk.com July 20, 2022

July 20, 2022

It turns out the FCC has already covered this in their rulemaking for 9-8-8<https://www.federalregister.gov/documents/2020/09/16/2020-16908/implementat…>. ?We decline to adopt a proposal to require multi-line telephone systems (MLTS) to allow callers to reach the Lifeline by dialing 988 and no other digits.? (I believe that ?allow? in the quote above should really be ?require?.) They go on to explain that they are given the authority to require this for 9-1-1 by Kari?s Law, but that they lack a similar authority with regard to 9-8-8. So, while it is not required for MLTS to support both 9-988 and 988. I still feel that it is a good idea to do so if feasible.

Exercise caution when clicking links or opening attachments, especially from unknown senders. It shouldn't be much different than 911. 9911 and 911 can both work just as 9988 and 988 can both work fine with most any PBX that can translate dial plan digits. There is potential conflict with systems that can't handle inter-digit timeouts to allow both 988 and 9888-555-1212, I guess. But in that case I suppose the expectation would be to dial 9988 and 9911 already..

Since it appears that various mail clients deal with the existence of "Reply-To" in different ways, it's honestly a bit frustrating that this isn't configurable per-subscriber within Mailman, instead of implemented strictly as a list-wide setting. Otherwise I could just log into my member options page for this list & configure it in a way that works for me. -- Nathan -----Original Message----- From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of Alex Balashov via VoiceOps Sent: Tuesday, July 19, 2022 4:38 PM To: Carlos Alvarez Cc: voiceops at voiceops.org Subject: Re: [VoiceOps] Mailman 'Reply-To' munging (was: Re: 9-8-8 dialing [...]) Indeed. The default destination of a reply should be the list, which is accomplished by the following Mailman config options: from_is_list = 0 reply_goes_to_list = 1 ???

Carlos Alvarez wrote: > Do your users still dial 9 from their fax machines? Not sure if serious or "haha your users probably still use fax machines" joke. So I'll give a serious answer just in case: I can't recall ever running across a single instance of someone who has their fax line routed through their "conventional" PBX. So they never dialed 9 from their fax machine to begin with. And also since nobody expects to be able to dial local extensions from their fax machine, we set up a separate dialing plan for the fax port on the ATA that does not require the external line prefix. -- Nathan

9-8-8 dialing when an outside line access code (9) is being used

I have never heard of this. What LATA are you in? Can you give an example NPA where you know this to be the case? As a consumer, if I were subscribed to ILEC without bundled long-distance, I would find such an arrangement both confusing and infuriating. Especially with near-universal mandatory 10-digit dialing. So you're saying that I can dial two numbers within the same area code the exact same way, but one destination is charged as a local call and the other as long-distance? What if I fat-fingered something while dialing (intending to dial a local destination but being off by one digit in the NXX) & the call connected? What if I was simply unaware that a given destination was long-distance? This sounds like a terrible idea all the way around. Was this also the case back when 7-digit dialing was still possible? You could reach a long-distance destination within your same NPA by only dialing 7 digits? -- Nathan -----Original Message----- From: James Cloos [mailto:cloos at jhcloos.com] Sent: Tuesday, July 19, 2022 10:01 AM To: VoiceOps Cc: Nathan Anderson Subject: Re: [VoiceOps] [External] Re: 9-8-8 dialing when an outside line access code (9) is being used NA> This convention is handy for those who still get charged for NA> long-distance, as you can't accidentally dial long-distance unknowingly NA> and get surprised by extra charges: except thsat it is 10 for the same npa and 11 for other npas, irreguardless of whether the call costs anything. at least in the npas w/ which i am familiar. so the 10 instead of 11 provides no value. -JimC -- James Cloos <cloos at jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6

What mail client are you using? Prior to Monday afternoon, "Sender" was voiceops-bounces@ (as it still is), "From" was the actual sender, "To" was (as you'd expect) voiceops@, and "Reply-To" was not set (unless perhaps the sender set it in their mail client? not sure if that was getting preserved or stripped). In this configuration, Outlook would reply to the sender if I hit Reply, or to both the sender AND the list if I Reply To All. Okay, fine. At least there is a one-button solution to auto-filling the list as one of the destination addresses. Since Monday afternoon, though, "From" is now getting overwritten to voiceops@, and "Reply-To" is being set to the original sender. A sign that "Reply-To munging" is occuring. In this configuration, as described in the post I linked to earlier, Outlook apparently honors the "Reply-To" header and *only* that header, as it doesn't matter if I hit Reply or Reply To All: only the original sender's address gets filled in the To field. I have to now manually backspace that out, and replace with the voiceops list address (assuming I even notice it and am not running on autopilot). (I suppose Outlook's behavior From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of Carlos Alvarez via VoiceOps Sent: Tuesday, July 19, 2022 4:30 PM To: voiceops at voiceops.org Subject: Re: [VoiceOps] Mailman 'Reply-To' munging (was: Re: 9-8-8 dialing [...]) If I do a reply on this list, it always puts the sender as the recipient, not the list.
