Good luck with that.  That subsystem has been gone over many times in an
effort to improve it.  The basic problem is that CDR is designed for a much
simpler time, when we did not have things like call transfers, 3-way
calling, call conferences, and the like, so it is maladapted for modern
usage.  A much better method is the CEL subsystem, which generates events
which can be analysed after the fact to create a much clearer picture about
how a call progressed.
