Omnitouch Protocoldex - Telecom Protocol Reference Comprehensive telecom protocol reference for Diameter AVPs, GTPv2-C IEs, MAP operations, 5G SBI APIs, and PFCP. Search and explore protocol specifications instantly.

I'm always having to look up or reference 3GPP specs and at a protocol level, what you can and can't do for Diameter/GTP-C/PFCP/MAP/SBI, so I made a Pokèdex for protocols: protocoldex.omnitou.ch

Hot damn. By "manually adjusted" do you mean tested it in the lab and updated the list? We've also seen some handsets that behave differently for emergency calls depending on the software version, but we've got no reliable way of picking up software version either, which just adds to the fun...

We pulled a list from our P-CSCF for those with active IMS registration, but that only told us VoLTE compatible phones. We tried to do the same for E-CSCF CDRs but because not a lot of emergency calls the data is patchy, and it's often OS version specific too.

Any idea how this is done? Is it just checking the IMEI TAC against a list of known good handsets? We've done a few VoLTE status checker tools and never got a 100% hit rate before.

Alas there is no database to compare against, in Australia each vendor is doing their own tests, but they don't share data, even with each other about which phones work and which don't, and the OEMs themselves have generally got no idea either.

This Netscape Navigator browser seems slop free, just got to activate this Bigpond trial CD and get online.

I want to use a browser that isn't just Chrome wearing a hat. But I want a browser I can use. The struggle is real.

A photo of the leather rear seats of a 1990s executive sedan with a built-in laptop that folds down into a writing desk, a corded phone, and a very bulky center armrest with a black plastic fax machine built into it.

A closer look at an example of the armrest fax machine, whose exterior identifies it as an AEG Olympia Roadfax

Learned today that around 1990, Mercedes-Benz briefly offered a "mobile office" package for the W126 S-Class that included a fully functioning printer, scanner, and fax machine built into an armrest.

Perhaps eSafety should have it explained to them that a "pull request" on Github is different to Grindr.

Handset / baseband manufacturers IMS stacks always come up with new ways to ruin my day. We're seeing certain Samsung phones stops sending RTP mid-call and instead send random unidentified data (Not IPv4/v6) making the UPF unhappy and drops the bearer.

Reading a bio of Claude Shannon and it crystallized a sense I have of how engineering culture has changed into tech culture. Shannon embodies a certain ethos that used to be everywhere, where the goal was to do really smart stuff, and spend your spare time on unicycles and flamethrowing trumpets.

Just downloaded it for Kindle, thanks for the tip off!

TIL that if you uninstall python3-yaml from Apt on Ubuntu it'll uninstall Netplan, breaking all networking if you reboot the machine...

That is exactly what I'd done!

Nokia Put a 4G Cellular Network on the Moon, but Couldn't Make a Phone Call Nokia's Lunar Surface Communications System was supposed to be the first 4G network deployed on the moon and a test for future crewed missions. Things didn't go to plan.

AI advocates advocating for more AI isn't exactly a headline, but Telstra is a public company whose focus is on telecom, it's kind of a stretch to argue that just because they're a big technology company in Australia that they should be developing Australia specific AI here right?
