In the real telephony world, one can buy a DID trunk without buying a
PRI. If one wants more than about 10 trunks (depending on provider), it
may be cheaper to buy a PRI instead of individual trunks.
Having said that, most of these VoIP providers have their pricing model
exactly backwards (they seem to only want to compete with Centrex, not
with regular PBX services), in that they charge a lot for resources
that are freely available and cost them little (phone numbers), but
very little for scarce resources (call terminations) that cost them
much more.
Cost isn't a determination of scarcity. Numbers are scarce in the fact that they get assigned out to a specific entity and for a time, it is associated with that single entity. Phone lines for a VoIP provider though can be shared amongst the entire customer base.
To be clear, I was not talking about global resources, just in terms of those of an VoIP provider. Adding additional channels requires adding hardware (PRI card, CSU/DSU, possibly more CPU power) and takes more network bandwidth. Adding numbers (which are plentiful right until they are no long available) incurs no other cost (well, maybe a small ordering fee).
A PRI circuit should be between $35 and $50 per channel, Split amongst 3-5 customers. Of course you have to then account for the data side of the network too.
Last time we discussed with our telco pricing on DIDs, it was $4/month
per 20 numbers. Anything more than a couple blocks required some
justification. I think it was basically to make sure we wheren't running
some form of scam and moveing from number to number.
So, you are paying $.20 per number, in TN. Last I checked here in Sprint Local Territory, they were $0.10. My deal with AT&T Local Services in SF (a year or two ago) they bundled some and so we ended up paying about $0.01 per number.

What I would like is to be limited as to how much of a scarce resource (channels) I can use, but not be limited as to how much of a plentiful resource (numbers) I can use.
