How is it irrelevant? Is it not the crux of the issue here? Many upstream providers are just Asterisk boxes forwarding traffic. Those boxes can be overloaded with a malformed SIP header; hell, most application switches get wrecked by malformed headers. What I'm trying to say is that money is one of those things where security is actually important. Trusting telephony, even as a signal and not source, is foolish. There are many better methods of deriving identity. My point, and arguably the point of the article, is that telephony is insecure, and I think it's pretty far from irrelevant... Please correct me if I misunderstood, I'm not trying to offend I just don't understand.
