I'm really curious about some #telephony inspired/parody stickers I and others have seen in #Philadelphia. Anyone know anything about these?

So @connections is opening a new exhibit in #Denver and looking for volunteers of various types. See the video for more.

old meets new
haven’t made use of the flipper much yet aside from some harmless fun and my new flipper tamagotchi pet.
kinda fun that it comes with a red box app tho
Can any #telephony geeks tell me why FXS port hardware is so phreakin’ expensive? I just want to plug an old analog phone into a Raspberry Pi.

On #reticulummeshchat #reticulum #reticulummesh #meshchat you can over #radio
1. run multiple #lora #rnodes on one computer.
2. make voice calls over #433mhz ( #ism band at low 12dBm power) between two #rnodes , but of course with delay.
I used #heltec #t114 (version 2 ) and two #lilygo #tbeam for
#VoiceCall #telephony
(un/like #meshtastic )
3. image files can also be transferred
With PipeWire 1.4 almost out of the door, let me introduce you to one of its highlights: Bluetooth telephony support.
This feature consists of a new D-Bus API which allows applications to manage phone calls using the Bluetooth Hands-Free Profile (HFP) protocol.
Check out my short tutorial on how to use the API from the command line and have fun calling! 
George Kiagiadakis · Introducing Bluetooth telephony support in PipeWirePipeWire 1.4 is almost out of the door! One of the highlights of the new release — which I personally worked on and presented also recently on my FOSDEM talk — is Bluetooth telephony support.
Wow, Prices for #3CX (non-hosted. self-managed) seem to have skyrocketed - crazy.
What's everyone else using these days? (Self hosted options please)
Dear #AskFedi,
I'm trying to call a Belgian phone number from France, using FR, LU, PL SIMs. Each time I am getting a message in German, telling me that the extension is not known.
The number is eight digits without the country code.
The number is supposedly callable from Poland.
WTAF is going on?

Speaking of gear that I'd really like to get up and running again, there's this Equinox SuperSerial hub that's been occupying rack space for a while.
I think I originally picked this up with a specific want to do something like the Dial Up Lan-Party mentioned elsewhere.
I wonder how fast you can get a stable dial-up connection to work over an upstream #VoIP provider like Twilio, if anything.
[#TLDR: JUST TELL ME IF YOUR TABLET CAN DO #CALLS!]
#DearVendors of #Android-#Tablets:
Off all the #Functions you can put into a #Specifications Sheet of your Devices there's one you should ALWAYS answer clearly on your #Website:
DOES YOUR TABLET [with #4G / #5G / …) SUPPORT MAKE PHONE CALLS?
Like: IS IT TOO MUCH TO ASK TO HAVE THAT INFO IN THE SPECSHEETS?
You're obviously able to list all the #Codecs natively supported and the user-available storage as well as supported Frequency Bands, WWAN modes, WiFi channel width and the Display Glass vs. Panel dimensions including DPI of the latter and whether or not it has a hall effect sensor to detect your overpriced 1st party tablet covers!
Now some folks may ask: "WHY does this matter?" or outright dismiss this as a problem.
Listen:
Not everyone is able or willing to carry two devices when 1 SHOULD BE ENOUGH and also some places (i.e. #Turkey) have #ImportRestrictions re: #MobileDevices, so having more than 1 #IMEI is already a "NOPE!" by the authorities.
- Also this isn't something one can "fix" post-purchase like installing #VLC to decode some obscure file format in Software: Either the #Baseband and #ROM support #PhoneCalls or they don't!
So why do NONE of the #Tablet manufacturers allow to #search or #filter for that???
- Bonus points if you have lazy fucks like #HMD (aka. #Nokia) who literally copy the #Safety & #Useage information for all #Smartphones and #Tablets and don't even bother to change "Mobile Phone" for "Tablet".
NO, instead one has to download an obscenely huge #PDF just to then read on page 34 that for any "#telephony" function you NEED YET ANOTHER DEVICE FROM THE SAME MANUFACTURER AND HAVE TO SIGNUP WITH AN ACCOUNT and even that level of #abuse WON'T GUARANTEE THAT IT WORKS...
- I mean, come on, this ain't some obscure functionality like #OMAPI to do some "evil sourcery" like managing an #eSIM that is in a #SIM-Card form factor!
Pretty shure A LOT of other folks have the same question and ain't willing to get yet another device & #SIM just to recieve the occasional call because #TechIlliterates can't be assed to send an #eMail or learn #XMPP+#OMEMO to message one...
- Obviously they same manufacturers are able and willing to specify f-stops of the built-in cameras and list EVERY SINGLE #WEARABLE they made and certify as 'compatible' with, as if anyone is gonna take their non-#waterproof #Tablet for a marathon or god forbid triathlon...

Heya internet, I'm in search of tags and accounts of people playing around with:
* older enterprise networking gear
* telephony gear and labs, particularly CO equipment
Seems like the kind of thing one should be able to find on Fedi :-)
i am always surprised by how little attention this carefully researched history of the australian hacking scene has received over the years. dreyfus manages to present a technically deep yet down to earth recollection that feels like a page-turner.
if you’re interested in 1980s telephony, x25 networks, BBSes, and minicomputer architectures like Prime, this book is a no-brainer.
it’s impressive seeing a teenager turn a breadbox c64 into a MILnet penetration tool.

This rat's nest supported Plain Old Telephone Service for so many decades here.
And, later, DSL, that brief but welcome always-on Internet service that replaced dial-up some years ago, before cable and fiber arrived on the scene.
If I wanted to, I could pull these wires out and run my radio coax through the holes, repurposing the disused demarc outside as a transition box.
I doubt the telephone company would mind. The line fell off the house years ago.
So long, POTS.

#Protip: If you call me, you better have your Audio legible and not sound like someone dropped a Iridium Satellite Phone into the Water Cooler tank in a Cubicle hellscape
- If you can't do that, don't call me but sent me an eMail like any sane person who values their (opponent's) time does!
Soviet phone socket. Seems to contain a lightbulb?! And two 1A fuses.
No tone, but it's not disconnected, something pulses a ~40V spike every now and then.
The fuses connect each input wire to the residential outlet. The lightbulb doesn't seem to be connected to anything, but has those two screws to connect it across the copper pair, presumably for testing purposes. Those 40V spikes would make it flash. It's normally under an opaque cover.
Interesting.
