Biggest difference is that wormhole will pass traffic between devices on different networks as long as both are routable. So it’s not limited to a local network connection.

The feature is called “Visual Voicemail”. Your carrier may support it, but if it’s like mine they likely charge extra. iOS works around it by just answering the call and saving a recorded message.

It’s carrier specific. Mine doesn’t do that either. iPhones seem to be the only ones that force it. Otherwise I get to sit through the same dial-in voicemail service as ever.

Ah, I see where I got confused. Yeah, CGNAT isn’t very common around here. I don’t think I’ve ever run into an ISP that uses it. I can see how that complicates things.

You really don’t though. I use wireguard myself under the same scenario without issue. You just need to use some form of dynamic DNS to mitigate the potentially changing IP. Even if you’re using Tailscale you’ll still need to have something running a service all the time anyways, so may as well skip the proxy.

Fingerprint sensors have been an interesting hurdle for Linux distros. Not one I necessarily would have anticipated either. The biggest question seems to come down to their security as well, given that there have been exposed flaws in the design of biometric hardware that tries to generalize its compatibility.

Microsoft has defined SDCP as a strong standard for TPM/Windows, but there isn’t an equivalent for Linux. Match on chip sensors have made things a bit easier, but there isn’t a standard way to communicate the validated authentication to the OS, usually relying on TLS.
