Not correct. 36CCS is the theoretical limit. In order to return <10% busy
signals, the ISP generally has to stay below around 90% busy-hour fill (thus
around 33 CCS), and in practice, since capacity is added in chunks, it's
lower than that.

Here's the question: Who pays for a call, the caller or the callee? Are
local calls SENT-PAID or COLLECT? If the ISP is receiving the call, then
isn't the norm SENT-PAID? In that case the ISP should pay less, because the
ISP is originating zero and the resi subscriber is responsible for the cost
of the call! If the ISP wants an 888 number, then they should pay!

You want long holding times, look at a teenager. The only philosophical
question you're legitemately raising is the one of flat-rate vs. measured
residential usage in general. I think the market, if it existed, would
speak to that: Users prefer flat rate. It has to get damn expensive per
month before users voluntarily bend over for measured. Also, data users
aren't all long hold times. This debate began over ISDN, where it's much
easier to do time-cutting (with fast call setup), yet telcos discourage it
in favor of analog/modem, which means long hold times instead of time-cutting!

So if you're losing money, raise your monthly rate!

True to some extent. But it's often the telco's fault: PRI installation
lead times are measured in months, sometimes years. We've had wicked busy
incoming hunt groups sit months and months while waiting.

Possibly true. ISPs are somewhat dependent (some, very) on telcos. Telcos
however seem not to want the ISPs as subcribers, period. Most don't want
the revenue. It ain't their old familiar voice business.
