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

Service notification lists (outages, etc)
by caalvarez＠gmail.com Aug. 31, 2022

Aug. 31, 2022

How do you smaller players maintain lists to notify people of issues, planned outages, etc? We can't get them to update 911, let alone who should get these. Right now it's rather manual in our CRM. It would be nice to send something out to the list say yearly, and ask them to update themselves with new employees or whatever. For frame of reference, we're very small and would notify a couple hundred people, with events less than monthly.

We are suddenly seeing a lot of this seemingly nationwide from Bandwidth and thinQ (which is a multi-carrier aggregator). Anyone else?

Numbers listed as spam by Hiya

LOL, no. One does medical billing, the other does customer surveys. In both cases, the call recipients have an established business relationship and "deserve" the calls. A lot of people just don't want calls period, which I get also. There also appears to be some point where the marking is automatic based on volume and short call duration.

Especially after we all jumped through a bunch of hoops & paid other sums of money to be part of the "STIR/SHAKEN ecosystem". If we also have to deal with actively registering numbers with third-party databases as well, what's the friggin' point? -- Nathan -----Original Message----- From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of Alex Balashov via VoiceOps Sent: Thursday, August 25, 2022 3:02 PM To: voiceops at voiceops.org Subject: Re: [VoiceOps] Numbers listed as spam by Hiya > On Aug 25, 2022, at 2:17 PM, Carlos Alvarez via VoiceOps <voiceops at voiceops.org> wrote: > > That feels so much like a mafia extortion plan. Pay us to not screw you over. Seriously. How are we even supposed to know about these registries, if not for this list? What makes them in any sense official? Nothing? Who put them in charge? Are there more registries? Do you have to pay the extortion for both registries to be sure? If not for the fact that it???s an expedient business decision, I think everyone here should refuse to comply in principle.

Numbers listed as spam by Hiya

Hi, We primarily purchase numbers from Telnyx and Peerless. Lately any number that we purchase is automatically listed as spam. I searched through both of their stocks for random numbers in random area codes (50+ numbers) and every time Hiya says it's likely SPAM. I presume they are marking any carrier where it's easy to get numbers spam. Has anyone fought back against this or are people just going with larger carriers like inteliquent/VZ etc? Regards, Dovid

How? I have no idea, all I can tell you is the experience we see. Maybe Fred's comment has some merit if Peerless is either allowing actual spam, or re-assigning numbers too quickly (for new numbers). Your porting experience is something I haven't seen, but we haven't mass-moved numbers in a long time. If Peerless is the common denominator... Oh, wait, have you checked the attestation level for these calls? Are the calls with a Peerless DID going out via Peerless?

Splitting voice and SMS
by caalvarez＠gmail.com Aug. 18, 2022

Aug. 18, 2022

We had an odd customer request, via a vendor trying to provide them with automated scheduling services via SMS. They are asking us to "release the SSID" to allow them to do SMS on the number, but we keep the voice. I'm unaware of this ability, and they even said that so far, most carriers won't even discuss it with them. Their service rides on the Twilio API, and I *think* Twilio uses Bandwidth. This number is currently with Bandwidth. So I don't know if that might make a difference.
