[asterisk-users] Call tracing - Asterisk 1.4

[Louwrens Benadé]

	That's the way how i have it workin. Of course, this wasn't done in
	one day, i've been working on details for weeks. Generally i use
CDR,
	and manipulate it with ResetCDR, NoCDR, and link them together by
	first uniqueid. This works great for IVRs, extension2extension
calls,
	outgoing calls, blind transfers, queues. So i can take any call and
	see what was done to it, where it was transferred, duration of each
	step and so on, so on. However it won't work for conferences (you
	don't know that person will join conference unless it joins, and
then
	it's too late to change uniqueid, first cdr may be already writted),
	and i haven't implemented that for blind transfers. But generally if
	you want all that in DB, manipulating CDR is the way to go.

	When you will have more specific questions, please ask, i'm sure
	somebody will answer :)

So I'm not the only one :)

Ok, because of my lack of knowledge about using the dial-plan, I've resorted
to using Trixbox (don't laugh). I've managed to find where the initial
uniqueid is inserted which I then pump into a variable, and from there into
the 'userfield' in the CDR.

The problem I'm having at the moment is that I can't figure out when the
next hit in the CDR takes place. I've found the macro that (I think)
generates it, but no matter what I try, I can't populate the 'userfield' for
the next event. 

So here are my questions:

1. Is the next event in the CDR inserted by ResetCDR or NoCDR?

2. Can I use a locally defined variable ( exten =>
s,n,Set(v_identme=${CDR(UNIQUEID)})) ) or do I have to use a global
variable?
