Well. In most places inbound calls are not metered. So order a
PRI. Divide the monthly price of the PRI by 24 or 30 depending.
Add the cost of a DID. Add some markup. Then sell unlimited
usage of one channel. Then maybe that's $30/month, truly unlimited
usage of a single channel.

Well, I guess there's technically a limit of some 43k minutes/month
on that channel...

But I don't think that's what Mr. Dovid was asking for.

Now some people might have a PRI with some spare capacity that
they're already paying for. So maybe they sell unlimited DIDs
to recover some costs on the spare capacity. They just have to
be careful that the unlimited folk don't crowd out the others.
And the unlimited folk have to be aware that in this scenario
it is a best effort, "don't complain if your number gets a 
busy," type of service. But nobody's getting screwed in this
case as you say later on in your not, Matthew.

But, anyways I don't have such an already-paid-for PRI with
spare channels that are going to waste...

To sum up, you can buy dedicated capacity, or you can pay for
usage incrementally, or you can be satisfied with a best effort
service that may or may not work all the time.
