My SIP Number (VOIP) while notionally an 02 Prefix can be used from anywhere. E.g. I use it from the Fring app on my iPhone. I’ve been able to do this since install (around 5 years).
Quoting from the article:

But more than all this, we call people not numbers.
Google got this and introduced Google Voice to fix the problem.
