I recently took up an assignment to make certain SIP phones operate on a not-too-abnormal corporate network. I figured that while SIP appliances are ancient, they would still support modern #LegacyIP things like NAT traversal, since this network has no #IPv6 and there were two layers of NAT to the SIP server. How hard could it be?

Two weeks later, I have seen things. My naivete has yielded to the confounding world of 2000s era VoIP stacks, when SIP interop was non-existent. I wish I didn't know

Wieso zeigt einem denn die FritzBox die Ipv4 Einstellung von Heimgeräten nicht immer an, selbst wenn eine Mac-Adresse bekannt ist

Why is this turned OFF by default?!

Jetzt bauen wir bis 2032 verpflichtend in jeden Haushalt ein aufwändig zertifiziertes und auditiertes IT System (Smartmeter Gateway) ein. Das NUR ein seit 30 Jahren veraltetes IP Protokol spricht. Alle Mobilfunkprovider jetzt bis zum Sankt Nimmerleinstag #LegacyIP in Ihren Netzen vorhalten müssen.
Sicherheit an der HAN wird nur per "self signed X.509 Zertifikate" mit 7 Jahren Laufzeit bereitgestellt.

The worst film I've seen this year -- War Of The Worlds (2025) -- also only uses #LegacyIP addresses rather than #IPv6 . But truth be told, that wouldn't have salvaged the cringe-fest which my poor ears and eyes had to suffer through.

I am not left trembling in shock and fear like H.G. Wells' original work would have done, but rather I'm stunned by the bad cinematography and poorly-done "modern day" framing.

Then to make it even worse, the Teams notification sound plays throughout the film...
