I wouldn't predict the demise of PSTN anytime soon.

In fact, the impression that I get from those in my business circles is 
that they don't mind paying for telephone services.

Where you see their point is on the receiving side of telephone calls. 
If 'anybody' can make free voip calls, then anybody will call. I'm 
meaning telephone canvassors/telemarketers here.

By having a callout cost, it is perceived that this hampers 
telemarketing - not entirely, but considerably.

So for the technical people, yes SIP is very inviting. For Business 
people, it's less so. Telephony has been has become perfectly acceptable 
in a 'you-get-what-you-pay-for' scenario.

Years ago, 3 introduced Skype. Then it gradually vanished. A flat 
'Monthly Plan' was also to blame. You could make International calls 
within your cap without the 5-minute fumble of loading up Skype to find 
your friends overseas weren't on.

The same phone also had SIP, but nobody I knew could figure out how to 
use it. To understand it, in my experience required a visit to an LCA 
event or Linux User Group. Fun for some, but a little bit to hardcore 
for the average caller. PSTN still worked - no config files.
