Scott--

I'm the guilty party. I've been trying to fix several CDR bugs,
involving stuff like missing times, missing changes in state (like
NO_ANSWER when the call was ANSWERED), etc.

CDR's are complicated by the fact that they record 3 events: "start",
"Answer", and "end" events. Add to that the fact that in most cases at
least two channels are involved, sometimes 4 or 5, or even more,
involving bridging, maquerading, parking, transfers, local channels,
AGI, conferences, and more...

Some cases were impossible to fix unless CDR's were attached to every
channel, 
and merged to collect the bits and pieces that sometimes were on the
wrong side of the bridge.

The result is that several more cases are more accurate, but also, that
rather uninteresting CDR's can be generated. In contemplating what could
be done to get rid of some of these, I sometimes have to ask, "is this
truly something we have to get rid of?"... In the meantime,
uninteresting CDR's with NO_ANSWER and billsec=0, should be easy to
filter out, right?

I will, in the coming days, look at some of the extraneous CDR's that
are generated, and see what I can do to get rid of them. It's not always
that simple.
If we ring a phone, for instance, and no-one answers it, is that truly,
really, something that no-one will ever be, could ever be, interested
in? (just a fer-instance).

I welcome your input. Complain up a storm. I'll try my best to make you
happy.
