[asterisk-dev] CDR Fixings

Fri Jun 1 22:34:27 MST 2007

I'm hard at work, reshaping the CDR code to handle transfers better...

I'll show you what I'm doing, and now's your chance to correct things!

Teminology:  HF=hookflash;  HU= hang up;  ->  = dials  A= Answers

Scenario 1: Simple. 152 calls 151. They talk. They hang up.
=============================================================================

Example output: (1 CDR)

No big changes here.

Notes:
Ugh. Changes for scen.5 loused up CDR#2 in this scenario... It should be
Zap/52, not a zombied 51... I'll check into it.

The first CDR is generated at the first HF. The second, when 151 hangs
up after dialing. The last, when 152 or 150 hang up. If 151 doesn't hang
up fast enough,
the 2nd CDR will record the time spent talking with 151; the 2nd CDR is
messed up. I'll see if I can start it when #1 ends... (before I worked
on Scen#5, Scen#4
generated only two CDRs! :))

Scenario 5: Zap Attended xfer: (152->151; 151 HF; 151->150; 151 HF; 151
HU;
                                    152/150 HU.)

Example output: (4 CDR's)

Notes: 1st CDR emitted on first HF; 2nd emitted on 2nd HF; 3rd emitted
when 151 hangs up;  Last when 152 or 150 hang up.

2nd CDR has MOH for app; it actually documents when 152 was played MOH
during the xfer. The 3WAY time started with HF #2, ended when 151 hung
up. For the moment, 
you can determine the 3rd party by finding the record with the same
clid, and a start time equal to the first CDR's end time. Basically CDR
#1 + CDR #4 account for the entire time that 152 spent connected to
151/150. You can just drop "MOH" and "3WAY" records if this is not
interesting.

As from above, you can probably make out that I'd like to keep the
"source" caller the same thru the sequence. I also try to keep the
uniqueid the same thru the sequence, but that gets hard when dealing
with multiple bridges that don't even share the same channel. I'd like
to put the 3rd channel in a 3WAY in the appdata field, but it's hiding
somewhere in the zap driver.

Any thoughts on what you'd like to see/ don't want to see... tell me!

More to come...
