Yes, there is a problem with CDR's in asterisk. There is a bug
filed <br>
against the problem, but no practical solution for it.<br>
<br>
The cure: use the CEL interface instead, and generate your own
<br>
CDR's (or whatever else you could bill from [it doesn't *have*
to be<br>
CDRs])<br>
<br>
The cause of the problem: An interesting combination of 3
operations <br>
being performed on channels, namely masquerading, and <br>
forming local channels; add to that the hardwired 'roles' that
channels<br>
are given (channel, and peer), and the final knockout: CDRs
are stored<br>
on channels.<br>
<br>
The above 3 operations affect CDR's because parking and
transfers<br>
can change the role that a channel plays (chan to peer or
vice-versa); <br>
Transfers and parking involve the masquerading, and sometimes
local channels--<br>
both these operations involve duplicating a channel. CDR's
are meant for the<br>
channel playing the "channel" role, and CDRs on channels
playing the "peer"<br>
role are tossed out.<br>
<br>
Transfers turn the above into a complex mush in which the
results vary depending<br>
on who transfers who, who is calling, and who is called, etc.
Because the CDR's<br>
are stored on the channels themselves, they pass thru many
filters and operations<br>
that vary based on the roles they play and the operations
performed, which can change<br>
in subtle ways from release to release, from one bugfix to
another, even.<br>
<br>
So, the best way to get around all this is to get the CDRs out
of the channels, <br>
And to do that, you either use CEL, or you build your own
event tracking mechanism, using<br>
whatever means available (I've seen folks use the manager
event reports with their<br>
own logic in perl, or php, or whatever to do the parsing and
storage). Then, you either<br>
turn the events into your own billing mechanism, or you
generate CDR's to fit into your<br>
currently existing billing mechanism. Doing this right<br>
and making it dependable is not an overnight sort of thing.<br>
<br>
I proposed a CDR generating backend for CEL (which I haven't
completed yet).<br>
I even started it, but got layed off before I could finish it.
I've generated a spec<br>
for CEL->CDR generation, involving something I call "simple
CDRs".This doc has<br>
been evolving with time, and needs to be updated. I
previously described "complex"<br>
CDR's in the spec that provided more fine-grained event
logging in CDR format, but I've convinced<br>
myself that the complex stuff can also be done via the
"simple" method, and so I'm<br>
about half way thru the spec, expunging the "complex" stuff.
All my examples have to be <br>
changed -- If you are interested in looking at my spec, you
can:<br>
