That 60% thing would not really surprise me. Alex Satrapa or Martijn van
Oosterhout can probably back me up on this. Looking at the way traditional
phone companies do their billing (Telstra, AAPT, Optus, etc) it is amazing
how inflexible it is and how much human intervention is required on top of
the complexity in their billing systems in the software that handles calls.
Moving things in to software as Kim suggests does indeed allow one to cut
costs tremendously, using generic computers and well written software to
habndle huge amounts of data extracted from some simpler hardware just makes
sense I imagine.
