Benny--

First, yes, all the examples I gave were for Simple CDR mode.

Next, the notation is simplified. A -> B  means channel: A   dstchannel:
B   (A and B are also contractions for stuff like "Dahdi/1-1" or
"Sip/bob-1")
start, ans, end are the 3 times (e2, e3, etc are event times (symbolic);
disp is the disposition field. linkedID is described in the doc.

I don't specify src/dest, in the examples, as they really don't convey
much without all the background description,
(if I said src = '101' and dest = '202' you'd have to know the
associated contexts, etc. -- a can of worms)---
but every CDR will specify those fields for the Dial (or whatever else
was responsible for activating the channel).

I also didn't spell out stuff like userfield, amaflags, callerid fields,
etc; it isn't that they aren't important, it just
clouds the examples to get too explicit and verbose.

The main thing about these fields is that they are in the list of CDR
fields and described in the CDR field section.

The "Party" field says which channel this CDR applies to. I use it
because the channel/dstchannel aren't always
going to involve the channel in question.  Usually, tho, Party will
either be the channel or the destchannel. Knowing
which one is the trick.

And, as a side note, the A CDR in my examples usually lacks a dstchannel
field, because it's not being activated by a dial--
it's being activated via an incoming call on an FXO interface. (or an
incoming SIP invite, maybe...)

And, if I'm missing info that would really, really, necessary to have,
or hard to inject from the dialplan, now is the time
to fight to make sure that it is in the spec.
