@apalrd Have you been facing issues with #WiFiCalling while running #IPv6mostly in #OPNsense ?
I can't figure out exactly why it breaks in my home network, since there are no misconfigured rules nor anything related - if I disable DHCP option 108 and assign old addresses to each client, it works; when passing through #tayga #nat64, it stops entirely.

All this because the carrier's servers are stuck in the last millenium, of course they are: https://www.netify.ai/resources/mobile-gateways/country/br

O2 UK łata podatność pozwalającą na geolokalizację użytkowników smartfonów z technologią VoLTE

Operatorzy GSM, dla poprawienia jakości rozmów, mogą wykorzystać standard VoLTE czy Voice over LTE, pozwalający na realizację połączeń głosowych z użyciem sieci 4G LTE. Zwykle do rozmów telefonicznych oraz SMSów wykorzystywane były starsze (i mniej bezpieczne) standardy jak 2G i 3G, a nowsze technologie zapewniały tylko szybszą wymianę danych. VoLTE...

Telefonieren über WLAN (WiFi-Calling/VoWiFi) verbessert die Sprachqualität & Rufaufbau, besonders bei schlechtem Mobilfunkempfang. EVS ("HD Voice Plus") sorgt für kristallklare Gespräche. Prepaid-Kunden können es auch nutzen! 📶 📞 🌐 #WiFiCalling #VoWiFi #Mobilfunk #Heise #lifehack

A #PSA for anyone living, staying, entering or even travelling to/from #Australia:

Apparently, #Australia decided to mandate it's #GSM systems to be shutdown because some #GalaxyBrainChair wanted to yeet #2G & #3G and demand everything to use #4G & #5G when in fact #VoLTE support is spotty at best and #EmergencyCalling oftentimes is explicitly hardcoded to not use #WIFIcalling or VoLTE as providing #triangulation and #LocationData via #SS7 is a desired feature when someone calls EMS, Fire Dept or the Police for help...

• So essentially #tourists and anyone who hasn't an explicitly fully VoLTE-functional device they tested and verified to also do #EmergencyCalls via VoLTE are fecked with no reception when they need it the most!

• This WILL KILL PEOPLE!!!

As much as we want to bitch about #GSM & #GPRS / #UMTS being #outdated and #inefficient, there are reasons to at least keep 2G available - ranging from lower power consumption to higher resilience in emergency situations.

• #NewZealand for example does shutdown non-#EmergencyCalls during severe #Earthquakes so that people trapped and/or in need of urgent assistance can get through to dispatch operators and everyone else has to get in line and take a number aka. use #SMS or if existing #Internet to say "I'm fine!"...

• If the Ozzies really need that juicy #UHF #SubGHz #Spectrum it's totally feasible to instead change the #allocations and reconfigure #CellularNetworks to use lesser bandwith for 2G (i.e. only keeping the absolute mininum of channels available for any service) and thus clear up space...

And to add insult to injury, Australia passed a #NorthKorea|n-alike #CellPhone #ImportBan for any device that doesn't do i.e. the bespoke proprietary garbage that i.e. #Telstra, #Vodafone and #Optus do with the #baseband modems of their #branded devices...

Seriously, which #TechIlliterate dickhead decided it's a good idea to do that #3Gshutdown in Australia without even a basic 2G network up and running at all?

• At least #Switzerland [AFAIK] still has #3G up and running (tho it would've been wiser to do it like #Germany and keep #2G as emergency fallback with it's functions like #CellBroadcast....

RANT=> Vorrei mettere totalmente al bando i sistemi OTP via SMS

Con la rete cellulare che abbiamo in Italia, e per il fatto che in molti luoghi chiusi si è schermati dal segnale mobile, di fatto crea tanto #digitaldivide ed è un modo ASSURDO e ormai fuori dal tempo per fare autenticazione

A casa la rete cellulare fa #cagare, il #wificalling ancora non è ben supportato dai gestori di fonia, e quindi quando per fare una transazione (avendo pure la mail) mi chiedono (PER FORZA) gli sms, SBROCCO 🤬

I've become a fan of #GrapheneOS since I overcame my disgust of Google and bought a used Pixel phone. @GrapheneOS is a great example of usable security.

It's easier to install and use than most other aftermarket #Android distributions I tried. And it has been a bug-free experience for me – until 1 or 2 weeks ago when the telephone stopped ringing when someone called. Phone calls did not even raise a full-screen notification any more. Only when I happend to watch the notification area was I able to see that someone is calling me. Most of the time, I only saw it when they had given up.

Then yesterday the phone finally rang again! Today, this was broken again. Until I found a workaround! All I had to do was to disable WiFi telephony – a feature I had enabled right after I installed GrapheneOS and which had seemed to worked well.

Update: According to @GrapheneOS, the annoyance I described is not related to #GrapheneOS but most likely caused by the carrier: https://grapheneos.social/@GrapheneOS/113046499971181147
