  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.
