SIP also has one major advantage than email does: we've not *yet* got
the same penetration that SMTP did when it started really suffering.
Although I do see exactly the same apathy to the problem in voice
service providers and network operators now that I did in ISPs 10
years ago: "not a problem yet, can't afford to spend time on that".

It's difficult to do *that* much: a lot of the counter-measures need
support from the endpoint vendors for various features.  A look at the
quality (or even existence) of mutual TLS and related things in almost
all UAs speaks loads on their interest in such matters!

i'll give 10 pounds (of the Great British variety) and a bottle of
sheppy's finest Somerset cider to whoever comes up with such a thing.
