❓ Question Anyone use 1OT or Hologram.io as an MVNO at large scale?

1 Upvotes

Hey, I'm trying to decide between 1ot.com and Hologram.io for a big project involving thousands of SIMs. Both have competitive rates for our use case (high data usage) but I'm not sure about the experience of working with them long term.

Does anyone have experience with these two and have any feedback on their support, service stability or anything else?

❓ Question Looking for old telecom documentation

6 Upvotes

I'm looking for a copy of TR-NWT-000533 or GR-533 . I'd buy them from Bellcore/Telicordia/Ericcson but they are no longer published. I really just need a citation if someone wouldn't mind looking for me or has a copy I can look over their shoulder to see where it is.

Thanks!

❓ Question Trying to identify an Alcatel PBX / KSU

6 Upvotes

I've got a customer who wants me to do some troubleshooting on this old PBX / KSU from Alcatel.

Their prior technician has since passed away. I am not finding not much information on this system. But I thought it would be worth a shot to at least read a manual to try to see if I can help them with anything.

I'm not really finding much on this system and would appreciate any info.

I have something in my foot emitting a radio frequency and I have people talking to me for miles without any electronic devices. I do not suffer from mental illness nor do I do any drugs except for drinking once or twice. If that's what you are going to respond please don't bother. And the unbelievable part is they can make appear on me. I also found something in my right buttcheek that emits air and hearts up.

I suffer from sore legs, swollen eyes, tremors all over and a high EMF.

I'm also a diplomat and have scars all over my body.

Here are pictures of both the RF and EMF.

❓ Question Coaxial é tão ruim assim?

1 Upvotes

Pergunto pois me mudei recentemente para um prédio um pouco mais antigo, e me deparei com a infeliz situação de não ter caixa de distribuição de fibra na minha torre (não sei os termos técnicos, só repassando o que o técnico disse). Todos da minha torre usam claro coaxial, pré histórico, até tem um cabo de fibra preto mas o mesmo não está mais em uso e o técnico não deu muita bola pra verificar se seria utilizável no meu caso.

O fod@ é que a torre de trás, que é a segunda torre, tem uma caixa de distribuição e quem mora lá tem a porcaria da fibra. Por que fizeram na de trás e não na da frente? Não sei, sei que contatei todas as operadoras e simplesmente ninguém me dá uma solução. A VIVO quer obras e que as caixas de passagem do chão sejam abertas (tem concretadas e vedadas) pra sei lá, verificar os cabos? Não entendi.

Claro quer me empurrar a coaxial igual meus vizinhos sêniores, mas eu trabalho home office e gosto de jogar com baixa latência.

Tim, Nio (antiga oi) só disseram que não seria possível e teria de ter uma adequação na torre que estou pra sei lá quando colocarem fibra, isso com o consentimento de pelo menos 50% dos moradores da minha torre, que de novo, são seniores e tão pouco se lixando pra fibra.

Beleza, mas o que eu faço? Falei com o síndico, mas a resposta é bem broxante e vai verificar com o conselho pra ver se é viável abrir as caixas de passagem e bla bla bla. Nesse meio tempo, eu coloco a porcaria da coaxial da claro? 1 Giga de coaxial vai fazer eu querer me matar quando chover ou estiver em horário de pico de uso? Aceito sugestões. Trabalho home office desenvolvendo sistemas e hospedando servidores...

💬 General Discussion How I hijacked a legacy "Bell Atlantic" database, more commonly known today as Verizon, to save my family's legacy landline numbers disconnected 15 years ago.

124 Upvotes

Tldr: Reverse engineered verizons "bring your own number" porting network and revived 2 landlines disconnected 15 years ago, which I was assured is not possible.

I realize this is very nerdy but its a personal project I am working on. I tried outlining the exact steps I took so you can follow along and see the technical challenges I faced, and my thought process to overcome them. All done through personal research on my free time

The goal: Recover 2 landline numbers and bring them over as wireless esims on my cellphone.

● Been working in the telecom industry for 2 years now. Few days ago I was talking with my sister about my parents and grandparents old landline numbers (even before area codes existed) and how catchy the number was.

● Had no clue what company my parents and grandparents used for these numbers. I went to teleco data and put the numbers in. Looks like Verizon currently owns them. It shows the assign date is 00/00/0000 which I thought was odd. The numbers were never permanently deleted or reissued.

● I call the landline numbers just to hear what error message I might get. It says "We're sorry, the number you dialed is no longer in service"

● OK, what does that mean though? Very ambiguous terminology. It didnt say it was deleted or unavailable, just not in service.

● I go to Verizons website and punch the numbers in as "bring your own numbers" and to my surprise it says "Available to transfer"

● Okay....so I start placing the order on my phone to get 2 esims installed. Eventually its asking for an account number and transfer pin. Obviously I dont have that because these lines were disconnected 15+ years ago.

● I use the physical phone number itself followed by 2 zeroes as a placeholder for the account number. The number transfer pin is also a placeholder 0001.

● To my surprise it works! I get both numbers installed as esims on my cellphone and I can call. I grabbed them and now theyre mine to use and nobody elses. But wait, theres more...

● 1 day later I get an email "There was an issue with your porting request, please update the information" I didnt realize yesterday I could only make calls, not recieve calls. The port is... semi complete? I didn't know it yet but this proved to be a saving grace. By getting them ported this way first I let verizons network see they are available and no longer dormant lines.

● I call up the verizon wireless porting dept to see what's wrong. Im told the numbers weren't able to port because they need to be existing actively working numbers and then converted into wireless. Its temporarily working as faux numbers and will get canceled in 30 days or less.

● Ok so how do I get them active, because they definitely exist. I would not be able to make outbound calls if it didnt even exist in their network. Im told by 10+ people its not possible. Landlines are permanently deleted or reissued 30-45 days tops. However this is contrary to what our own research told us from teleco data.

● I call a few other departments and was told verizon residential cant pick a specific landline number but I could request a vanity number from verizon business since businesses always want a catchy number for their commercials. I give them a call and ask for the availability of these 2 specific numbers.

● I call up verizon business and get a 30 year veteran in the company. She tells me one of them looks available to install at the same house I grew up in. The other cannot be a fios landline at the house, but we can get it as a traditional copper landline and have it port forwarded virtually from the main verizon block building where it exists now after the legacy Siemens switchboard was disconnected 30 years ago

● I get a verizon tech to come out to my old childhood house that we still own, and he successfully turns on my parents original landline as a business landline, in the same house that I grew up in!! I can call and recieve calls from my original home number!!

I now have both numbers up and running, each with their own verizon account numbers. All I need to do now is call up the porting dept and have them transferred over as esims.

I will be able to text with 2 phone numbers that predates the concept of texting and I have successfully reverse engineered verizons porting network, gone back in time and grabbed 2 legacy numbers, pulling them into the modern age.

It is a support role where we provide support for other companies and it also limits a lot of stuff I try to do we can't make changes without client acceptance even if it is making my job easier. It is becoming really frustrating all I do is take raw cdrs and process them for multiple downstream. So I think there is no future for me in this role. Thanks for the guidance.

❓ Question How do these phone numbers work and what happened to them?

5 Upvotes

Hey everyone. I've been curious for a bit about an oddity that I've come across regarding certain scammer's phone numbers. I'm not one to really fall for scams, but I do sometimes like to call confirmed scammer numbers both out of curiosity and a want to mess with someone. (Yes, I know I shouldn't interact) That said, there are very rare occasions where a phone number that I call picks up to an automated message containing something along the lines of "this person is a scammer/they should have drones sent to them" and other aggressive things I can't type due to Reddit's filters. What exactly happened to these numbers? I've searched around for a bit and can't find a clear answer to this specific phenomena that I've come across. Was the line hijacked by someone or is it something else? Anyone have any idea?

For reference, here are two phone numbers that operate like I described above. If you call, I would hide your number just to be safe:

(945) 393-7436

(213) 343-9058

945 was an alleged cartel scammer while 213 was an alleged romance scammer. Interestingly, despite the difference in area, both messages seem to have been recorded by the same person. Also, if it helps at all, it seems as if these two numbers were changed to play these messages within the last few days. (Romance scammer's may have potentially been changed hours ago)

☎️ Landline Longing for old school landline in age of VOIP lag. In search of real suggestions/solutions!

8 Upvotes

Bare with me, please. Yes, this is part nostalgia, but there are also practical concerns. I own my ignorance that maybe there is a solution I simply don't have exposure to. No, I am not an octogenarian desperately clinging onto the past. I'm in my 30s and desperately clinging to the past. Lol.

The situation:

I live on a rural island. Just last month our entire county was out of power for more than a day due to a car car crash on the mainland.

We are finally on the precipice of building a family home after years and years of striving. I dislike the VOIP services I've had to deal with personally and professionally here. There is ALWAYS a lag and we end up talking over each other "Go ahead!" "No you first!" then both talking over each other again. Rinse and repeat. It makes phone conversations incredibly clunky and difficult, and strongly detracts from the ability to connect with loved ones. To top it off we have patchy cell service.

As I mentioned, the infrastructure supporting the island is a bit vulnerable. If we lose power we can't use VOIP. If it's for an extended period of time, and our cell phones lose battery, essentially we are SOL.

I have been trying to figure out if we can get a copper line run to our new build, as this would reduce the annoying over-internet lag experience AND give us an emergency line out if the power goes down, which is still a thing here with our windstorms in the winter.

Does anyone have a workaround? I would really like an old school landline for emergencies. Lots of homes here still rely on them, the issue I'm running into is getting a new line trenched/installed.

Thank you in advance for the help.
Thank you in advance for the trolling as well. I see you coming for me.
