That's not true, the carriers are compensated through CABS (carrier access billing) based on number of minutes, not number of connected calls.

Carriers have to accept traffic from other carriers, even if they have not paid their CABS bill.

Right now, no one is paying anyone. That's why fair cross-carrier compensation and flat-rates are a big talk in the FCC instead of what's called "Tariff rates" which vary by carrier and by destination.

Freeconferencecall.com exists because of CABS and having very high tariff rates. They do NOT want lots of short duration calls. That doesn't help them at all.
