The speaking clock at the Main Post Office in Kraków, on the corner of Potocki and Wielopole Streets.
A speaking clock is a telephone service that provides the exact current time when you call a designated number.
It was once an essential tool before digital clocks and smartphones became common.
The recorded voice—often of a radio announcer—would announce the time precisely, synchronized with official standards.
Today, most speaking clocks are historical curiosities, but some still operate as reminders of early telecommunication technology.

Hardware I returned to Xfinity this afternoon. The Arris telephony modem was about 20 years old. The cable box / DVT was not much younger.
We dropped cable TV, VOIP, and stopped renting modems (bought my own Arris S33v3) very recently, saving hundreds of dollars per month on the bill.

Now the other two are ported - all the #analogue #trunks are ceased and all traffic to and from the #PSTN from this #PBX is now #VOIP (using #PJSIP trunks on #FreePBX )
I disconnected all the analogue lines as #Openreach leave battery on them, that way they show as RED alarm on #Asterisk and won't be selected for any calls (worst case is they return a busy trunk status and the route will go to the next trunk, but I've taken away all the analogue circuits from every PSTN route)
@lackthereof no, it's not because unlike #Phones and #PhoneNumbers, #eMail is not necessarily traceable by circumstances.
Whereas with eMail (and any #asynchronous #communication) you don't have that requirement.
cock.li which natively supports @torproject / #Tor useage with an #OnionService, unless said provider explicitly prevents you from doing so, you can use not just Tor but also other techniques to make it extremely hard (not necessarily impossible, but at least unfeasible at scale!) to get tracked down.Or to put it simple:
So either way a phone number is just a horrible means of doing that.
OnionService which can only be shutdown effectively by sabotage aka. (more or less figurately) "unplugging" it.I mean, it's not as if I didn't gave @signalapp a fair chance.
So any #Messenger service that requires a #Phone Number for signup and/or useage is truly not a real replacement and inherently makes PROVEN WRONG assumptions [i.e. that it is legal and possible to obtain a phone number anonymously at someone's juristiction] about it's customers' ability to shield their privacy…
THIS is why I am going fucking ballistic on #TechPopulism aiming at #TechIlliterates because it's spreading a "false sense of #security" whilst completely disregarding absolute fundamentals when it comes to the underlying systems.

Everybody who is even a little bit nerdy at heart, go check out @connections video on recreating the first telephone call. I know I'm looking forward to part 2!

📞 THE VOICE THAT CHANGED THE WORLD - IN HAVANA!
March 7, 1876 — Antonio Meucci, an Italian immigrant working in colonial Havana, Cuba, developed his revolutionary "teletrofono" in the workshop of the historic Tacon Theatre. While history credited Bell, it was Meucci's Cuban laboratory where the telephone was truly born. Golden tropical light streamed through colonial windows as he connected rooms with copper wire and wooden acoustic tubes, creating the first voice transmission device.

I'm taking another look at jmp.chat today for various reasons (mainly that voip.ms is, while much better than nothing, also kind of frustrating) and ended up here, this is an interesting manifesto:
[Call-me - Claude Code가 당신에게 전화로 연락합니다
Call-me는 Claude Code와 전화로 실시간 상호작용이 가능한 초소형 플러그인으로, 작업 완료 알림이나 의사결정 요청을 전화로 전달할 수 있습니다. 다양한 기기와 호환되며, OpenAI API를 활용한 음성 인식 및 합성 기능을 제공합니다. MCP 서버를 통해 로컬에서 실행되며, ngrok 터널링을 사용해 전화 서비스와 연결됩니다.
One (1) #telephone number successfully ported to #VOIP, one more left to go (there's 2 pairs for main and aux line, provisioned on same number but those will go to 3 channel #SIP trunk)
For some reason #Openreach have left battery on the pair (I would have thought they would want to recover capacity on the line card and it would just go dis, as there are still going to be a handful of customers remaining on #PSTN circuits.
I thought a lot of "analogue" trunks these days were literally just a SIP ATA connected to the copper pair at the Telephone Exchange (or from a street cabinet) but it looks like Openreach really are getting the last out of the old #SystemX kit!
There is no dialtone or even NU tone, just some noise..
