VOIP security

[#1]

In the age of sim swapping, I tend towards using my landline for security such as receiving 2FA codes from banks etc because I believe it to be more secure.
But in the age of VOIP, am I correct in believing this i.e. that a landline gives me more proection from hackers.

Does VOIP make a landline just as vulnerable as a mobile?

What makes you think a standard landline is not vulnerable?

Later Voip hardware support encryption. To quote Cisco:

"The ATA 190 Series supports the latest encryption with Transport Layer Security (TLS), Secure Hash Algorithm (SHA-2) and new Secure Real-time Protocol (sRTP) cipher suites."

You mean "What makes me think a standard landline is less vulnerable than VOIP"

Because a standard landline is not on the internet and thus not accessible to hackers in Russia or North Korea etc.

The age of VoIP started well over a decade ago. Companies have been learning in the meantime.

I once received a call from Nigeria (if I remember correctly) with a UK-based number. Which was a bit naughty. (it was over the internal company network, and not routed externally - bar over privately leased lines)
