It's is just waiting for the first one to arrive.. The mechanics are just too appealing for spam-like businesses.
Imagine a telemarketeer script that dials lists of VoIP addresses. Instead of having
to pay for each call they use cheap Internet bandwioth. The same cost savings we use * for applies to the telemarketeers also.

caller. I'm very sceptic about that: if I record a salespitch and later fan it out to a list
of known ENUM hosts, then it would be indisciminable from an actual phonecall...
... at least for the start of the salespitch, and that's bad because then you've already
crawled to your phone and picked up the handset.
Blacklisting spammers is harder too, compared to SMTP spam.
How is it that different?

That's oversimplified. You wan't people that you don't know yet to be able to contact
you. (I want potential customers to call my business number).
All kind of SMTP scanning and filtering techniques won't do good in the VoIP world
as you cannot examine the whole message. It's realtime..

Yes, it's oversimplified, but you're missing the point. The point is that if we don't have individual components that can be secured to the point where there is an authentication method for accepting calls, then we're trying to bail the boat with a sieve. The "middle" of the network will be smart for a long time, though the control of the middle is moving all the way to the edge (users able to control their own whitelists/blacklists/methods) and the middle is certainly getting closer to the edge (SIP-based proxy and PBX systems getting cheaper, but probably not household items for a long, long time, if ever, for the bulk of the market.) So, I'm content with trusting that the spam control will be handled by the "middle" of the network, as long as we have some way of authenticating calls between the middle and the edge.
PS: Businesses will always be subject to VOIP Spam - they _want_ unsolicited calls. There's nothing you can do to prevent salespeople from calling your business unless you either (a) have a human filtering the calls, or (b) push your customers or potential customers through a lot of voicemail routines which will get them to hang up. That's reality. Spam-reduction techniques can cut down on a lot, but those filters will always be looser for businesses.
