While I am ready to DTMF, I fear that the rubber ring around the speaker fits onto a now-long-gone hand-held telephone receiver design.

1936 #Poland
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.

  • Because a Phone "Line" (regardless of whether it's POTS, ISDN, VoIP, GSM, VoLTE, …) and #telephony in general are designed for realtime communication, they inherently necessitate an active, ongoing connection.
    • Even if it's just some App/PBX/… to connect to the provider and constantly state "I am on the network and able to recieve calls!" (with PSTN networks, there a physical line that gets assumed to have a phone connected)…

Whereas with eMail (and any #asynchronous #communication) you don't have that requirement.

  • So unless the provider is being taken over or otherwise "cooperative" there's no means for a sender to know where, when and how a message was retrieved unless the recipient wants the sender to know of it!

Or to put it simple:

  • You can ring up someone and thus circumstantially verify the chain of #PhoneNumber -> #IMSI -> #ICCID -> #SIM -> #IMEI -> Device -> Location -> Owner quite quickly.
    • Whereas you can't positively verify whether an eMail address and/or #XMPP+#OMEMO account belongs to me unless I want you to know that it does!

So either way a phone number is just a horrible means of doing that.

  • And don't even get me started on the fact that legally speaking noone truly owns their number.
    • Because even if you got some spechal case number (like UPT was) you still depend on neither regulators nor telcos to not block or otherwise interfere with it. Which is in contrast to say an 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.

  • I wanted #Signal to be good - honestly...
    • But I'm old enough that things rarely are that simple as #TechPopulism & #Propaganda claim it to be.
    • Just like 5th grade #SexEd is not a substitute for Endocrinology, Gynecology and Andrology and actually licensed, medical professionals.

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.

📞 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:

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..
